Hi John,
wiring diagram we dont have actual but my feeling tells me, this could be a good practice for John to create it!? 😉
Just in few words….
the slipring has 12 wires in I use it like that:
1= MOT1 Pitch
2= MOT1 Pitch
3= MOT1 Pitch
4= MOT2 Roll
5= MOT2 Roll
6= MOT2 Roll
7= SDA (RX in case for NT IMU and I recommend to take only NT-IMU!)
8= SCL (TX in case for NT IMU and I recommend to take only NT-IMU!)
9= VCC (5V from IMU port)
10= GND
11= VIDEO OUT of Runcam
12= GND out for Runcam
I dont need the Powering for Runcam! But maybe you can use the GND twie and take the 12th for 5V Power seperate!
* NT IMU!!! — in short words, never without! Why? No more I2C Errors, no more ferrits and no more 7V level, but over all, NT-IMU Logging, the best tool to vind vibrations on the Copter and Gimbal!
Actaul it is very Easy, you don´t have to solder it by your self (like my first NT CC3D IMU few month ago!) meanwhile you can order it incl. the Storm32 or as sand alone NT IMU http://www.ensys.lt/product/storm32-nt-imu-module-v2-0/
