New cape coming up, PCB out for printing...

New cape coming up, PCB out for printing… And yeah, I did put an AVR on it too. I know, I know… Give me more time to learn about the PRUSS and I’ll remove it. That cape does power the BBB, though. In theory it does, at least :wink:

Cool. What’s it do?

tell us, what does it do?

I’m guessing it’s to with model trains :slight_smile: http://www.aerodynes.fr/ and https://www.youtube.com/watch?v=Rfj6WpUd0N0

@Bert_Lindner that’s correct, it’s the next iteration of the controller. It is used for model trains, of course, but on a more generic level, it contains a PWM motor controller with speed sensing (BEMF), as well as a 2-chip solution for controlling 32 relays - one at a time, plus four individually - , which is not that easy to do on a small board like this! I’m curious to see how the switched mode power supply on the bottom right corner will perform, I used the design helpers from TI to optimise it…
