Re: An Arduino Pro Micro With USB-C
Cre Wallace
Hi everybody, had an issues with that solution, my PC doesnt see arduino after i put connector between them (PC -> typeC -> micro -> arduino(wemos)). Tried to ping wires with multimeter signal for data+- passed. Connecting again through micro, start answer again.

Hi, thanks, this does the trick indeed. However now I have to switch settings every time when I change between the two types of Nano.... So better use one type in one project. (My crawling robot uses one for each segment, currently 5.)
What strikes me as strange is that the Nano type-C is newer than the type with micro-USB yet requires an "old" bootloader.
Here at SparkFun, we refuse to leave 'good enough' alone. That's why we're adding to our line-up of Arduino-compatible microcontrollers once more! The SparkFun Qwiic Pro Micro is a revision of the original Pro Micro and is, overall, functionally the same as the previous version. The board is the same size as the original Pro Micro but we added a few additional features by shrinking down some components on the board such as a reset button, Qwiic connector, USB-C, and castellated pads (this makes it really handy for you custom keyboard creators out there)! Think the Pro Mini except with an ATmega32U4 on board and full USB functionality.
The benefit of the reset button is to quickly reset the board or place it into bootloader mode without the need to take out a piece of jumper wire. The USB micro-b connector has been replaced with the USB type C connector. The through-hole pads have castellated edges for each pin to add a lower profile in your projects should you decide to build it into another assembly during production. Finally, a Qwiic connector is populated on the bottom of the board to easily add Qwiic enabled I2C devices to your projects!
The CAD files are probably not going to be updated anytime soon as other projects and products have our burning attention.Good eyes wrt USBC branch. For this product, it got a bit messy. The Pro Micro C 'revision' turned out the be very popular with the original maintaining is popularity. We are trying to maintain master for folks that still have or want to purchase the microB connector version.
I had a similar issue with the board, which I ultimately fixed. Out of the box, USB wasn't working at all, but I hooked up an AVR programmer and could get the blink program running. Still, none of the USB-related sketches would run and the serial port never showed up. Due to the nature of the USB 3 connector I couldn't test it directly, but I did hook up a microUSB board to the pads under the board. Same issue though, error logs complaining about enumeration errors. Spent an hour digging through forums to find that the 5.1k resistors were almost certainly the problem, and that this design is bad. Very, very carefully shorted them (what are they, 0402?) with wire, as suggested, fired it up, and everything worked fine. Would have preferred to replace them with 22 ohm resistors but I already spent so much time just getting this board into the state it's supposed to be in from SFE, I just didn't want to deal with it anymore.
will there be a 3.3V /8MHz version? According to this guide 8MHz is recommended for 3.3V for projects where low power consumption is key.( -arduino-power-consumption)"reducing the clock speed of the microcontroller can shave a few milliamps off the supply current. "
I designed and printed a PCB for my MIDI controller project with a modified Arduino Micro microcontroller essentially built into the design. I swapped out the USB Micro for a USB-C type port (just using the 2.0 protocol). Although I can program the board via ICSP, including getting it to run my Arduino sketches (which I have tested by having it light up the LEDs in a certain pattern, which works as expected), and the fact that it receives power via USB, the problem is that I cannot get the device to connect to my PC over USB - it is not recognized as a USB device, and cannot seem to send or receive data over USB. I'm not sure if I've done something wrong in the design or if I am simply missing something, but could use some advice, as in order to function as intended, the board will need to be able to communicate over USB.
I feel a bit embarrassed for taking up people's time on such a stupid error I made (and admittedly didn't even provide enough information for anyone to be able to figure out for me, despite all of your patience and helpful advice), but at the same time I am both relieved I figured out the problem and grateful for all the help I got on this post, I'm not sure how long it would have taken me to figure out without your suggestions. I learned a lot about the layout of arduino boards, the purposes of various components in said boards, the importance of double checking footprints, and about better practices for asking for assistance.
Hi I want to connect arduino NANO to my laptop with Type-C (USB-C) ports (on below image left side [4] and other side 3). Now I bought a USB-C to USB-C cable, because it appeared to be the right tool, but the Arduino is not even powered by this cable. if I use regular USB 3.2 Gen 2 Port (on below image [5]) everythings for fine. but this usb-c ports not recognize the Arduino NANO even NANO's power LED is not switching ON.
There's no real speed benefit for the C-Duino as it only communicates through D+ and D- pins, identical to the pro micro, but I don't like having a cable for every single device on my desk. I designed the PCB on EasyEda, ordered it on JLCPCB, and the components on LCSC. I have not yet tested it on more advanced cables with built in controller boards such as Thunderbolt 3 but basic USB-C to USB-A cables work fine. The GitHub repository with all of the pictures and PCB files is linked below and I hope more people can make this project in order to perfect it in the future. If you have specific questions, feel free to message me and ask. Detailed instructions on construction are coming in the future but for those more advanced, all of the necessary information can be found on the GitHub.
The Leonardo, Leonardo ETH and Micro differ from other Arduino boards in that they use a single microcontroller to both run your sketches and for USB communication with the computer. The Uno and other boards use separate microcontrollers for these two functions, meaning that the USB connection to the computer remains established regardless of the state of the main microcontroller. By combining these two functions onto a single processor, the Leonardo allows for more flexibility in its communication with the computer. It also helps to lower the cost of the board by removing the need for an additional processor.
I got it powered via a normal phone charger with micro usb right now. But it would be neat to have the camera power on and off together with the printer And if i could get away without a buck converter ?
We can finally tell you all about the new product we had announced for SPS! Today, we are excited to expand the Arduino Pro range with Opta, our first micro PLC with Industrial IoT capabilities.
The Arduino Opta is a secure, easy-to-use micro PLC with Industrial IoT capabilities. Designed in partnership with Finder, a leading industrial and building automation device manufacturer.
However, that means extra cost and extra space for the dedicated communication chip. I guess that's ok for most applications, but I'm curious; from reading a presentation explaining the details of the USB-C PHY layer I would think that it should be rather doable to implement the same logic directly into any better micro-controller (like an ESP32). I say that because the link speed is spec'ed at 300kbps at low impedance at 1.125V (shiftable to and from 3.3V e.g. with PCA9306) via two pins. Sure, then a lot of processing is happening on the logical data to the physical, but that should not be "too hard"TM to implement, right? Or am I missing any good reason/complication not to do that?
Addition: Apparently there are a few micro-controllers with built-in capabilities (thanks @Justme), like the STM32G071. There is even an official discovery kit (STM32G071B-DISCO) and wiki entry.
Most notably: I can buy the MCUs without PD PHY functionality, but the applicable ones (for my use) with PD PHY are vaporware in practice. Furthermore, I need the rather specialized peripheral set on the microcontroller I already use, so switching to a different uC is not possible. Even further, PD is just a tiny bit of the overall device functionality in my case, so choosing an MCU based on that is a bit of a stretch.
So today, I'll be trying out my soldering skills on reviving an Arduino Pro Micro with a broken off USB port. This instructable might help fix any broken micro USB port I suppose, you'll basically have to figure out the steps to fix your port. Keep in mind that this is my second instructable and my camera setup is nowhere near good enough for documenting this in perfect detail. I'm hoping someone else will pick on this instructable and help out with resources. :)
Here's my Google photos album for the entire project.
Dear god....
1. that is an insane amount of patience. If I see lifted pads, the board goes into the dead PCB bin...
2. The microusb connectors without through holes to help hold them onto the board are not meant for applications where there isn't a housing around them to keep them from getting ripped off the board - for a brand-name board, you really expect better.... As far as I'm concerned, using a connector like that on a development board is a design flaw.
Integrate the micro PLC with users' existing machines, devices, and production lines, or combine it with other elements in the modular and versatile Arduino ecosystem, from small and smart sensor-packed modules to SOMs to gateways, for end-to-end solutions that can be customized to meet any need.
