Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

But if we don't care about USB and we redirect the console to a COM port?

I always come up with this stuff when I'm unable to test (Pico just went up in a puff of white smoke  )

I've had the worst weekend...I hereby confirm that 24V on the Pico's 3V3 does not result in a satisfactory ending. Unless you like white smoke.

Same thing is true when you push more than 2A through the L298. 18200 is far more forgiving...it simply shuts down.

Ouch....    
Smoke makes things work. When the smoke gets out, it stops!

This is not a "Good Thing" (TM).

Alas poor Pico. I knew him well, Craig.
