3DR 500MW Radio Telemetry 433Mhz Air and Ground Data Transmit Module for APM Pixhawk - V3

Dimensions: 26 x 53 x 10.7mm (without antenna)
Power Supply voltage: 5VDC (from USB or JST-GH)
Transmit current: 100 mA at 20dBm
Receive current: 25 mA
Serial interface: 3.3 V UART

Status LEDs
The radios have 2 status LEDs, one red and one green. The meaning of the different LED states is:
Green LED blinking - searching for another radio
Green LED solid - link is established with another radio
Red LED flashing - transmitting data
Red LED solid - in firmware update mode

Connecting to Pixhawk4
Use the 4 pin JST-GH connector that should have come with the radio to connect the radio to your Pixhawk4’s “Telem 1” (“Telem 2” can also be used but the default recommendation is “Telem1”).

Connecting to a PC
Connecting the radio to your Windows PC is as simple as connecting the micro USB cable (which should have been included with the radio) to your PC. The necessary drivers should be installed automatically and the radio will appear as a new “USB Serial Port” in the Windows Device Manager under Ports (COM & LPT). The Mission Planner’s COM Port selection drop-down should also contain the same new COM port.
