My friend and I each put together a build as follows:
fc: naze32 rev6
motors: cobra 2204 2300kv
escs: littlebee opto 30a
battery: tattu 1300mAh 75C S3
frame: shendrones krieger dtf225
we got the boards soldered and flashed firmware (Naze 1.14.2) with cleanflight 1.2.4. I have two issues:
1) using the motor test in cleanflight, only the rear 2 motors spin.
2) the 5v outputs on from the fc (e.g. the one next to the rc input pins and the middle row in the esc/servo/main headers) are only outputting about 1v. as a result (I believe), the radio transmitter won't power on.
Using a voltmeter I verified that I'm getting 5v into the fc. I'm using opto escs so I'm powering the fc using the 6th pin in the main headers.
I'm not sure how to continue troubleshooting from here. Any suggestions would be much appreciated.
I'm attaching a diagram of the wiring as well as a photo of the wired board, but please ask any questions if I could be more clear or provide more information.
