I'm trying to expand the number of output pins on a Mega so that I can use a lot of 28BYJ-48 stepper motors, preferably with the accelstepper library.
My thoughts: Each PCA9685 board can manage 4 ULN2003 drivers. there can be 62 different boards so theoretically there are 248 stepper motors i can use. But...... How to achieve this?
Sorry my native language is Dutch...
