Single sided BOB for STM32F4xx Black pill

[avizienis]

Hi everyone, just finished testing my ghetto version of BOB for the popular Black pill by WeAct. Was wondering if anyone would be interested in the design files.
Properties:

1. 4 axes outputs (3 limit inputs);
2. Single sided PCB;
3. Optocoupled inputs;
4. Buffered 5V outputs;
5. Onboard downconverter. Could be 7805, I used a micro DC-DC converter.
   It's based on earlier version of Phil's BOB but stripped down to the bare minimum. To minimize routing I had to adjust the existing map files slightly, so that all outputs (except PWM) are on one side of the chip, all inputs on the other.

That looks good!
If you publish the design I will link to it on the driver page. If you are going to do so you should give the board a name and make a PR against the test branch for a new map file for the board.

Hi Terje, all project files have been uploaded to:

I will also try to create a PR in a sec

I see you have added a map file to your repo. Can I add it to the driver and add entries in my_machine.h and driver.h for it?

Yes absolutely, I remember creating a pull request for exactly that some time ago

You made a direct commit to the repo, not a PR - I have missed that. It was lost when I moved the code to the new home from my subversion master - I'll fix that.
