Hi guys,
I want to present you the smallest member of Jaluino, Jaluino CELL as
it was named by Sebastien. Look at it as a prototype and a proposal.
The board is designed to be used on a breadboard and for rapid
prototyping.
This version use the USB bootloader of Albert and use the red LED as
boot mode indicator. Right now the red LED is connected at RA4 pin but
I'm open to suggestions. Unfortunately, the space is very small and I
was forced to remove the jumper which allowed disconnection of the
LED. You can do that removing the limiting resistor (but is nice to
have a boot mode indicator). Also not all components fits on the top.
One diode and three resistors (all smd) are soldered on the bottom.
The green LED is for power indicator and the blue jumper is for power
select (USB or external). The external power must be 5V regulated.
Why no regulator on board? To be able to address any project,
with any consumption requirements.
The board don't have an ICSP connector (no more space) but having
external pins, the microcontroller can be easily programmed if you
insert the board on a breadboard (without the fear of bending pins).
Well, the initial version was a lot bigger but Sebastien suggested that
if can be of maximum 5cm long it can benefit from the cheapest
Seeedstudio service and I considered it a good advice..
I hope that this board will be useful for someone.

It looks good (haven't patience to look closer). However why did you mix through hole with smd? (except the connectors, use only smd onboard) The lenght can be reduced with at least 10-15mm if miniaturization is your need. All vias are below the microcontroller, some people does not recommend such tehnique, however I see no problem only if this board is factory manufactured. Maybe the board has a good purpose, which I can't see it because I have never used solderless breadboards and have no intention to use from now.
Using a breadboard:
- is not safe, has poor contacts, a lot of signal interferences, the final stuff breadboarded can work different than the prototype (if the breadboard user will manufacture a prototype after playing with wires) and that is a good way of wasting time understanding if the bug is a software or a hardware one
- the user is missing the key of playing hardware: learning soldering tehniques, learning PCB design techniques, understanding the bitter relation between the initial ideea and the final product

:-D maybe, who knows. Better to be prepared.
It is only the atmel. I had to chose from Atmel, ST, Philips, and
another one, don't remember. No Microchip available. :)

Hi,
As many others I'm scared by the smd so only 1206 size components
used. Those through hole components helped a little in routing (which
was made auto with some manual routing at the end so, not sure...). I
want to keep the 22pF capacitors as through hole (in that area are
many "veins") and I can try to use for the remaining, SMD variants.
Thank you for the tips.

One more: if you are routing paired signals (like USB D+ and D- ) try to keep at least the same impedance for both of them (meaning atleast the same lenght and traces routed as one pair). USB has a specific impedance for D+/D- (even USB1.1).

Vasile, I can understand your concerns about using breadboards, but I
think you missed the "big picture". The board is, as Vasi put it,
"for rapid prototyping". I don't think it is intended to be used in a
final product where such concerns would be an issue. Its much much
more time consuming/expensive to prototype a pcb only to find later
that you need to make a change. With a breadboard it's normally just
a matter of swapping a couple jumpers around. I think the board is a
pretty good idea.

This Jaluino CELL looks nice. I agree that vias can't be under the SMD
PIC. As for the capacitors etc, I don't mind if they are through hole
components since SMD's are harder for beginners to get.
If you want, there could be two versions of this, one with all SMD
(and vias under SMD), and one with only PIC SMD (make the resistors
stand up). Vasile is right, don't mix.
So, where is Jaluino MAX? May I suggest 18f67j50 or 18f87j50.
I think all beginners use a breadboard. Are you saying that you did
not? Bread-boarding is a good cheap way to learn electronics. I
personally don't have the cash to mess up PCB's and components, so I
make stuff on breadboard first, but I have to be careful to modify my
schematic every time I move something. Of course I'm sure micro-
controllers and cell phone's can't be designed on a breadboard. It
depends what are building. In this case, it is a learning tool.

Brian,
Both you and Vasi might have right. What I'm trying to say is there is a time when the lack of trust in own possibilities and acknowledges make the use of solderless prototyping necessary and a time when a project can be done without any initial prototyping tests and works from the first hardware revision and some firmware iterations. Prototyping might be necessary only for analog stuff, but never for digital stuff where things are clear if the originator of design understood what he is doing before starting the job (and not after he already did it).
Use this board with pleasure, it looks Vasi has done great progress in understanding how to design a PCB.
BTW, Vasi take off D1 diode which is not necessary(I've told about this several times on various topics). You can understand whyonly if *understand* the Millman's and superposition theorem. Else you'll put that diode in all your projects till retirement.
Both theorems are here:

I have never used solderless breadboards. And I will never use. Of course I have used 100mil pre-drilled breadboards, in which routes are connected with soldered (or rolled) wire-wrapping. I will search some pictures of old projects from that era, just see how looks 300 to 500 wired routes...If someone did such thing once, will never do it again, it's the best way of learning...from mistakes.

I agree with you on solderless breadboards: I've used them a few times
and wasted a lot of time on chasing issues that were not related to
the circuit. So okay for connecting a led, but that's it. From this
perspective the cell makes sense: the circuit you depend upon is on
the pcb and not on the breadboard. On the other hand: a jaluino board
with a small breadboard does the same.
The pre-drilled solder breadboards (or perfboards like Wouter calls
them in his shop) are my prefered way of working. Way more flexible
than pcb's, allow for incremental work and don't suffer from the
solderless breadboard instability. I use it for almost all 0f my
projects and have few dozen of those boards working.

Hi guys,
I attached the project with the last (I hope) modifications. The
previous one had an USB connection error (due to changing two USB
connectors during the design and lack of pins information for the last
one used) - solved now. Also, I was able to add again the boot/testing
LED jumper. Removed the diode and a filtering capacitor is on back.
The board can be used also as USB-to-serial converter.
This is how it looks now:

Hi Matt,
I like them too but from my experience, are not so durable as the B
ones. Also, here is a little paradox. If I try to replace the big one
with the small one (be sure I wanted to use it), I'm forced to
increase the board size and it will be more expensive.
Here are the last modifications. Repositioned two resistors on the
back and a via moved under usb connector. And this is all.

Hi Joep,
If the project is a big one (not only a few components), or a specific one which need a PCB with complicated shape, the time spent for soldering wires at least at two ends on a perfboard and cut the perfboard is longer than the time spent to design and manufacture a board, even a homebrewed one (using toner transfer).
This can be understand with difficulty by nowadays computer guys, however imagine that it was an era when there wasn't any computer and homebrew PCB was manufactured by hand using a nib and ink (carmine ink). In that days manufacturing a PCB with 10 integrated circuits onboard tooks for me about 8 hours.
Another trick you can use (and I see nobody did here, or at least didn't show) is to create a "heart" design, which match with various applications. Is much better than using jaluino/arduino/picolino because can be transfered from one project to another using copy and paste. In this fancy way you don't have stacked boards or other silly solutions which can blench your hear. Any time when have to design a project using for example PIC64F2011, you copy the "heart" and put it on your new design. The same with pheripherals (SD card, I2C memory, USB, USB/RS232, stepper driver etc). Designing a board is less painful than writing the code (at least for me), anyway you all know that a good code has at least ten-twenty revisions since works as it shout, while a good PCB has only one. The key is: "don't rush!".
work with joy,
Vasile

Same thing as Jaluino, but more memory and pins. Keep the header pin
layout of Jaluino, and add more pins.
I think all of these boards need both SMD and through pin versions.
SMD versions would be cheaper to manufacturer.

> SMD versions would be cheaper to manufacturer.
That's true. I've once asked my PCB assembling company, and they told me how PCBs are populated:
1. solder paste is applied to the top side for SMDs using a stencil
2. top-side SMDs are placed in the paste
3. top-side SMDs are soldered (infrared, hot-air or the like)
4. bottom-side SMDs are glued in place without solder paste
5. the glue is dried. This takes its time and therefore costs money
6. top-side THTs are placed
7. top-side THTs and bottom-side SMDs are soldered (possibly selective, wave soldering or the like)
8. bottom-side THTs are placed and soldered by hand. That's expensive, of course.
So, cheapest is SMD with parts on one side only. Next is THT only. Then come mixed SMD and THT with all parts on one side. Then SMD on both sides plus THT on top side only. The most expensive are PCBs with SMD and THT, both on both sides.
I'm not sure where to put "SMDs on both sides, no THTs" as it could well be that no glue is necessary then.
All of this only applies to automatically populated PCBs in perhaps 100 pieces or more. For low quantities, THT might even be cheaper as no solder-paste stencil has to be made.

If you're in the mood of creating PCBs, what about a Jaluino Bee:
- xbee compatible socket: you choose which comm. board (bee) you want to use (XBee, Bluetooth-Bee, USB-Bee, home-made hope-RF-bee, ...)
- *-bee board could be plugged below so pin headers from 18fxxxx would be accessible
- or, *-bee board could be plugged above, so JaluinoBee could be plugged on a breadboard
I don't have any xbee board or the like, but it seems it becomes more on more popular, some *uino even provide a bee socket as part of the main board (look at Seeeduino Stalker). As you say, having a widely used standard socket like this is quite interesting.
Bee socket provides many pins, I understand only few are needed for minimal setup: power, DIN, DOUT (tx/rx). Maybe also CTS/ for reset system. I'm not sure about all the functionality of other pins, but for instance one is a PWM output proportional to signal strength. There sure will be debates about which pin should be kept and which shouldn't...

Next, may I suggest you do an open-source Eagle design for a FTDI

I hate paying $15 for these adapters, when there is perhaps $5 of

Thanks for the link to LadyAda -- I enjoy her projects but somehow I
missed that one. Again it is a bit smaller than I need, but yes that
is very useful since the licensing is compatible with what I was
looking for.
It is hard to say about the cost, without looking at the specifics.
Perhaps $5 is too low, but $10 seems too high. Surely they are making
a profit at $15?

It use USB-Serial (CDC) which is automatically recognized by Linux

Hi Jerome,
--
I was about to reply about CDC device on Jaluino Cell thread, but here you are. I've experienced the exact same troubles with some recent experience with Jaluino (medium).
Basically, I tried to remove the configuration part responsible for telling host system this is modem (remove USB_V25TER). This will prevent host system from sending AT chars. The problem then is it's not recognized anymore, it actually depends on your kernel version. There's a patch in CDC kernel module, making this "empty" configuration recognized. Use >= 2.6.32 (couldn't tried though, my linux box is sick).
So, FTDI or CDC ? FTDI indeed requires a driver, but doesn't CDC too ?? FTDI is also widely used, it's become a standard. I would prefer a USB converter acting as a FTDI device, but I think implementation is far from easy (and maybe not open).
Cheers,
seb

Microsoft started off quite bad on the cdc driver. They do improve but
iirc there is still a bug with toggling RTS / DTR on XP. Don't know if
this is resolved in newer versions. FDTI drivers are much more stable
in my experience. Downside is you are not allowed to use the FTDI
drivers with other chips than FTDI. There are however implementations
of the driver on PICs that seem to work okay.

Hi,
Has anyone considered microchips MCP2200 usb to serial converter chip? It's being sold for less than US$2,00.

Hi Kiste,
It seems it implements a CDC class device, so as for me (and Jerôme) problems remain the same. At least when using kernel < 2.6.32. Not a real problem...
Cheers,

I like the dying enthusiasm at the end of every topic like this.
So you can see my jaluino cell "simulation" in attach. In fact is the core of a puzzle design I've started.
Which will have many modules...

How you soldered the USB connector? I mean there, where the pad play
via role (GND pin). Hmm, I looked better, not need to solder the GND
pin on both sides because you can solder the pins from the metallic
case on both sides. For the crystal I guess you used pins from an IC
socket? Also, is easy for reset button and no problems on male
connectors. So, it is doable.

This USB connector is the worse (from the 4 or 5 types available) for soldering without metalized holes.
A wire wrapping is soldered first on the component side or the pad ring and get through the solder side where is cut.
When solder the USB connector on the solder side, you solder both the wire and the connector pin...
Hmm, I looked better, not need to solder the GND

I'm using only Augat sockets, those are friable or sold as individual pins.

I've once bought a breadboard and plugged a voltage regulator and a bcd to seven-segment-decoder on it. That was, if I remember it right, the only circuit I ever made on a breadboard. Since then, and this is about 20 years later, I make the more complex prototypes on perfboard or stripboard, and the simple ones in "hedgehog"-style.
However, for both hedgehogs and perfboard, this device can be useful. It can be plugged in a DIL socket.

No, this connector is bad from all points of view, it can be changed either with a mini surface mount or with one of the host/device USB inline connector. In fact is the first time I'm using this large height one and convinced myself it was a good point to not use it.

Maybe a mini-B USB connector because is easy to borrow a photo camera
cable to connect it (or using the cable from Pickit2 programmer)..
Using the "inline" USB connector is not good - is not popular among
users.

This is what I suggested but you reported it was actually taking more space in this design, for it's a SMD component, IIUC.

Yes, and I was right. Then Vasile Surducan redesigned the board and
managed to make it shorter. Still, I'm not convinced it will fit in
the 5cm request...
V.Surducan will make it without taking in account the 5cm limit
because he is making it at his CNC Router.
