Both Pro Micros are sharing the same RX pin #23

From a quick look on the PCB layout it seems like both Pro Micros are connected together using the TRS cable by pin number two (The RX pin of the serial port). If it's true then the right (slave) side won't be able to send data to the left (master) side.

Helix is working correctly. No problem.

Because Helix software doesn't use USART in Atmega32u4.
