Hello I spent some time and learned a lot building a version of your product. I am running servo vent controls and and pwm l298n x 6.
I figured maybe some of this is already on 1 board. Found maker pi with 2 motor controls and 4 servo outlets and 7 sensor comports…
Maybe someone has used this maker pi and can explain if it’s useful for Mycodo?
I also saw this yahboom 6wd robot expansion card.
Figured it has a lot of the puzzle on one board but I got no experience beyond copying your stuff.
Maybe there is already a robot control board with multiple motor drivers and pwm servo pins and maybe i2c inputs…
