The system provides a full-duplex link using HopeRF's HM-TRP modules running custom, open source firmware. Interface to the module is via standard 5V-tolerant TTL serial / FTDI USB serial. Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through the 3DR Radio configurator and AT commands. Features Small size and light weight Receiver sensitivity to -121 dBm Transmit power up to 20dBm (100mW) Transparent serial link Air data rates up to 250kbps MAVLink protocol framing and status reporting Frequency hopping spread spectrum (FHSS) Adaptive time division multiplexing (TDM) Support for LBT and AFA Configurable duty cycle Built in error correcting code (can correct up to 25% data bit errors) Demonstrated range of several kilometers with a small omni antenna Can be used with a bi-directional amplifier for even more range Open source firmware AT commands for radio configuration RT commands for remote radio configuration Adaptive flow control when used with APM Based on the HopeRF HM-TRP radio module, featuring an SiLabs Si1000 RF microcontroller. Other Dimension: Air / Ground module (no include SMA connector) : 17m x 35mm / 17mm x 59mm Weight: Air / Ground module: 4.6g/16.8g (include cable and antenna) / 7.2g/17g (include antenna) Package content Air Module(915Mhz) x 1 Ground Module(915Mhz) x 1 UART 4Pin cable for Air module 300mm for MWC x1 UART 4Pin cable for Air module 300mm for APM x1 2.5dbi Antenna for two module x2
