Thanks for the detailed description, I have a Molex Micro Fit cable like you in stock, also with black, yellow and red. At the weekend I will measure the pins....

sorry for that question: I want to reproduce with the M5Atom RS485. Could you upload the sketch/code here, please? I tried in Arduino ide but got an error> no balboa_helper.h...

Hello Schubi1, thx to you. I'm waiting for delivery of the m5atom with rs485, so we have time enough.

My M5Atom is arrived. Pretty little helper. Ready for the sketch... Q: Are you using the power supply from the Balboa motherboard or via USB-C?
