Features:
- Model: YRRC Radio Telemetry V3
- Frequency: 433Mhz
- Receive sensitivity: -140dBm
- Transmit power: up to 30dBm (1000mW@9600bps)
- CP2102 USB to TTL Chips
- Air data rate: up to 250kbps
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. *2Km range is only possible when used in proper weather condition, very low air data rate and line of sight Ground-Air. With default settings and full transmit power on both ends the range is around 300-500 meters.
Specifications:
- 433MHz Frequency Range
- Receiver sensitivity to -117dBm
- Transmit power up to 20dBm (100mW)
- Transparent serial link
