3DR Radio Telemetry Air Module for APM and APM2 - 433MHz

Communicate via UART (serial) at a great distance. This module is used at autopilot functions of drones. (which are then controlled via the remote computer )
However, the module can also communicate serially with your own (Arduino) system at a great distance: Radio 915MHz 3dr module telemetry with arduino. (915MHz is used, but this module with 433MHz works the same)

An adapter cable and antenna are included. The color codes of the cables are as follows:

• Red: +5V
• Black: GND/ground/min
• White or Green: RX of Radio module
• Orange or Yellow: TX from Radio module

Specifications:

• Works on 433MHz
• Receiver sensitivity: -117dBm
• Transmission power: 20dBm (100mW)
• Data rate: up to 250kbps
• Range: up to 500 meters (depending on ruis in environment)
