Two Microcontrollers

Are we allowed to use two microcontrollers, because i need to use 10 motors and since we cannot program the signal splitter, i have to use another microcontroller…

So are we allowed to ??

I’m assuming that you’re talking about VRC rules…

No, you’re not allowed to use two microcontrollers:

If you want to use 10 motors, you could use the Y cables, but some of the motors would be “tethered” to each other. You could also trade in your current microcontroller/reciever for a Cortex - it has 10 motor ports.

If you don’t need to control all 10 motors simultaneously, you can use the additional Buttons to change Operational Modes, to control the various motors separately.
