Two Arduinos will connect to each other through hardware serial. One is the display and maybe wifi. The other monitors temperatures, throttle, etc. and sends data to the motor controller
Arduino I
This is a repurposing if John's old temperature logger. 2 7-segment LED digits and a wifi module. It also has a 1-wire Dallas Semi temperature module but reading from the module with the Dallas Semi library causes hiccups in the main loop.
