A kid could pick motors from a pile of vastly different hardware and have a working robot in an hour. Tear it down and the next class can do the same.

That’s extremely challenging. I will watch this and hopefully learn.

With just 1 board design, each is capable of running either 1 BLDC, 2 DC motors, or 1 stepper. It only discovers its role at runtime.

I designed a generic board like that, but it came out really expensive. This is the board:

If you are interested, I could open the design. Check out this thread.

New driver board DRV8412 / 70-V, 6-A Dual H-bridge motor driver

As the title says. Versatile Quad-PWM driver, capable of running two brushed DC motors, one BLDC or one stepper. Takes input from 4 PWM or 3 PWM logic, which means it could run with pretty much any MCU out there, PWM up to 500kHz. Which means you could experiment and test with them all using only one driver. Even better, since it requires only up to 4PWM, you can pair two of these with one MCU and drive 4 DC brushed motors independently for a 4-wheeled quad-powered platform with independent whee…

Question, do you have anything to do with SLO Cal Poly? Or slomobile is just something else?
