I am now waiting for the 5-gang box from homedepot to get started on the actual build. I'm a little concerned with the overall size of the project with the box I've got, but I already tried a 4-gang box and it wasn't really big enough for the guts plus the switch, fuse, and signal cables.
I wired up a test circuit and was able to verify that I know how to wire this thing for mains power. The test was a success.
I ran the following in an interactive python session:
import Adafruit_BBIO.GPIO as GPIO GPIO.setup("P8_10", GPIO.OUT) GPIO.output("P8_10", GPIO.HIGH GPIO.output("P8_10", GPIO.LOW) GPIO.cleanup()
