Would like to use the matrix display. Looks like it takes a whole XIAO (ESP32-C3). how to connect it to a second XIAO (of same) that is used as a system controller? Is USB an option? would I2C be available on XIAO that is driving the display? Does the display actually use all pins? Can system XIAO also drive display?
Driving a matrix display often requires significant processing power, especially for animations or high refresh rates. This can make it difficult to use the same ESP32-C3 for other tasks.
Thank you for this confirmation. How to get controller XIAO to talk to display XIAO? Can USB be used or is I2C still left available on display XIAO?
you can splice multiple boards or use mort than one pin to drive each board
you can use IIC to communicate with multiple XIAO if you desire
