915MHz Radio Telemetry Air + Ground Module Kit 3DR Radio System Compatible Description: 915MHz Radio Telemetry Air + Ground Module Kit 3DR Radio System Compatible The Radio telemetry system is based on 3DR Radio system and 100% compatible. It's designed as an open source Xbee replacement radio set, offering a lower price, longer range (approx one mile) and superior performance to Xbee radios. Ita??s available in 915Mhz and 433Mhz; and in the following configurations:A serial board (for the air) and USB (for the ground). The system provides a full-duplex linkA using HopeRF's HM-TRP modules running custom, open source firmware.A 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 - Available in 915MHz variants - 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.
