The Radio telemetry system base on 3DR Radio system and 100% compatible.

It has 6 positions conectro Molex 2 way full-duplex communication through adaptive TDM.

The firmware is open source. The connection to the module is through OTG.

Firmware upgrades and configuration support Arduplanner. The configuration is also possible via the configurator 3DR Radio and AT commands.
