Single TTL 3DR Data Radio Telemetry Kit 915Mhz w/ 3Dbi Antenna for APM2.8 APM2.7 Flight Control

Single TTL 3DR Data Radio Telemetry Kit 915Mhz w/ 3Dbi Antenna for APM2.8 APM2.7 Flight Control

Description:
- Single TTL 3DRobotics 3DR Radio Telemetry Kit 915Mhz Module for APM2.7 APM2.6 APM2.8
- The 3DRobotics 3DR Radio is the ideal way to setup a telemetry connection between your APM and a ground station. Small, inexpensive and with great range, the 3DR radio uses an open source firmware which allows us to do things that cannot be done with other radios.
