Just wondering how to use/program/wire the power expander
It’s very easy. Plug your motors into the female ports on the Power Expander, use extension cables from the male ports on the Power Expander to the desired ports on the microcontroller, and plug in a battery. There’s no programming involved. Programming wise, it’s as if your plugged in the motors into the microcrontroller directly.
Look over the wiring diagram listed here: https://vexforum.com/wiki/index.php/Power_Expander
Also read the attached PDF file, as it contains important information about the Power Expander.
