Organizing the DriveBoard schematic in Fritzing (and "hi all" and e-stop doubt :)

[Xoan Sampaiño]

Hi all!

I'm (from Spain, repprapper, 36) new here in the Lasaur Nation. What
amazing project :)

I'm planning (actually, thinking... long time target) into build one.

And first, I'll try to mimic the electronics board behaviour with some
spare components I have laying around (rpi + arduino UNO, a couple of
TB6600, solid state relays, and so on.). It's just for learning.

But Fritzing schematic is a little bit messy for me, so I've begun to
organize it using "net labels" and to split it into parts (like
microcontroller, power, steppers, connectors, etc.).

Final file is attached, with the same layout and with the schematic
fully routed.

But I am not an electronics guy, and most of the parts are easy to
understand even to me except the e-stop system and relay. Are the two
jumpers:

1. jmp1: to bypass the e-stop switch?
2. jmp2: to alow 5V stay powering the board when e-stop switch is open?

The relay used is a SSR in DIP package, connected in parallel. I guess
I can use a standar SSR relay, right?

Thanks, and thanks for this big, big opensource thing :)

Hi Xoan,

The jumpers are optional and only needed when you want to configue the
DriveBoard so the BeagleBone stays powered when the e-stop is pressed.

Also the small SSR close to the e-stop is controlled by the e-stop and
switched the 5V board power.

If anyone is interested, I redrew the schematic in KiCad (because I
found Fritzing too buggy). It can be found at
