HOWTO drone wiring (1): FPV-Cam/OSD/VTx/Telemetry

One picture tells it all 一張圖教你接線

Writing on the phone screen is tough, readable?  ;)

The tricky part is the power flow. On OSD, voltage comes from the video-out side, and is fed back to the video-in side powering up the camera.

For telemetry, North America uses 915MHz, Europe uses 433MHz. Google for detail.
