VRX Radio Module lite - 868 Mhz (Europe)

The VRX Radio telemetry system is designed as an open source Xbee replacement radio set, offering a lower price, longer range (approx one mile) and superior performance to Xbee radios. It's available in 868Mhz (Europe and other countries that don't allow 915Mhz); and in the following configurations: serial board (for the air) and USB (for the ground).

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.

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 Radio configurator and AT commands.
