Description

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.
