• Just to keep you posted, I flashed the cutting edge build onto the board & ran that code, I'm getting fffffffe when I run peek32(0x1000120c).toString(16) which is great, but when I try to connect to my i2c device I'm getting Uncaught ALLCALLADR!=0xE0 - PCA9685 connected? which is progress but not super encouraging.

    There's definitely a chance its either the soldering on the board or some other issue so I'm going to inspect that again first. I've had a previous revision of this board working although using different pins for i2c. I'll try and rule out any soldering or connection issues before taking too much more of your time :)
