An easy tutorial about how to install 3DR TELEMETRY 433mhz or 915 mhz on Micro PIX4 and PIXHAWK. 3DR telemetry installation is quite easy
but you need to solder cables directly to the air module.
The tricky part is find the right way to connect RX and TX: in some cases, you have to reverse those, in other case connection is straight.
Here it is the connection pinout:
PIX4 GND Telemetry GND BLACK
PIX4 VCC Telemetry VCC RED
PIX4 RX Telemetry TX YELLOW
PIX4 TX Telemetry RX BLUE
If telemetry doesn’t connect, revers from JST connector, yellow and blue cable.
