The 3DR Radio Telemetry 433Mhz 1000MW with 2~3km Data Telemetry has an independent signal amplifier (1W). Both modems here have the same design and can be used both in the ground station and in the air, and each also has a Micro USB TTL connector. The small omnidirectional antenna has a range of several kilometers, with a bidirectional amplifier a longer range is achievable. This product is based on HM-TRP radio modules with Si1000 8051 microcontrollers.

Frequently Asked Questions
What is the typical communication range of this 3DR Telemetry kit?
Under open-field conditions with clear line of sight, the 433MHz modules can reliably transmit telemetry data up to 2–3km. Actual range may vary based on antenna height, obstacles, and RF interference.
Can I use these modules with both APM and Pixhawk flight controllers?
Yes. The kit includes a 5-pin cable tailored for APM and a 6-pin cable for Pixhawk, allowing direct connection to each controller’s telemetry port without soldering.
How do I update the firmware on the telemetry radios?
Connect the module to your PC via Micro USB and use the open-source firmware tools available on the 3DR Radio GitHub repository to flash or upgrade firmware. Ensure both air and ground units run the same firmware version for proper pairing.
