I’m using the UART on my Raspberry PI 3B for serial communication and need RTS/CTS functionality. I also would like to use all three relays on the automation hat. The problem comes in with CTS being mapped to BCM 16 (Pin 36 on the header) which the automation hat uses for relay 3.
Is it possible to remap relay 3 to a free GPIO? https://github.com/pimoroni/automation-hat/blob/master/library/automationhat/init.py
BCM 25 looks like a good candidate since it is conveniently brought out next to the spi pins for easy access. My next question is where would be a good spot to cut the trace connecting BCM 16 and connect the new GPIO?
