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. It’s available in 915Mhz ; and in the following configurations:, serial board (for the air) and USB (for the ground)., Documentation:, Radio Configurator(Air module need a USB-UART tool like FTDI to configure):, Board schmatic:, ,
RCTimer Radio Telemetry Kit 915Mhz
The RCTimer Radio telemetry system base on 3DR Radio system and 100% compatible.
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.
