A word of warning about i2c errors and 3rd axis boards. I have just fitted this 3 axis board to my gimbal and I found it worked perfectly until I plugged in the 3rd axis board and then I got tons of i2c errors. I tried all the usual stuff like ferrite rings shorter cable, twisted cable ect ect. all with no joy, so I thought I would do a continuation check on all the connections and check the voltage supplies.
To my surprise the pins that fed power from the main board to the extension board where at the full 16v of my battery rather than the 5 v they should be. So I reckon when I first plugged it in the voltage has fried the extension board and is now giving me a load of errors.
I known the extension board is faulty because I plugged in another one I had and powered it externally and it works perfect with all 3 axes showing no i2c errors.
So if you plan on using a set up where the voltage to the extension board is supplied from the main board, do yourself a favour and check it first!
