915MHZ CUAV V3 3DR RadioTelemetry System for APM APM2 AMP2.5 Flight Control w/ Antenna

915MHZ CUAV V3 3DR RadioTelemetry System for APM APM2 AMP2.5 Flight Control w/ Antenna

Description:
- The 3DR Radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range and superior performance to Xbee radios. This listing is for 915 Mhz; and in the following configurations:  serial board (for the air) and USB (for the ground).
- open source firmware.  Interface to the module is via standard 5V-tolerant TTL serial / FTDI USB serial.
- The SiK firmware includes a bootloader that permits radio firmware upgrades over the serial interface, and radio firmware with configurable parameters. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through the 3DR Radio Configurator or AT commands.

Test data:
- Range:800M (57600 buad rate)
- Note:CUAV RADIO V3 version with Micro USB port as APM 2 flight control
