Hi! I'd like to control my A5 via a node js script running on an RPi via the UART pins on the Pi.
Should this be able to work?
I'm controlling the A5 through my mac and a USB/Serial cable at the moment, but would love to use less hardware when I get this set up permanently.
I have my pi sending serial to my compute over the same cable, but when I connected to the clock nothing came through. I'm happy to troubleshoot more, but want to confirm this should be possible before banging my head on the table for a night.
The other thing is I would love to power my Pi using the A5's power supply. I see the external power pads next to the serial pins. If I step the 9V down to 5V, should there be any issue running my Pi off of this power source?
