Hi everyone, I'm very happy to announce something that 3D Robotics has been working on since late last year in cooperation with a few very talented developers. Today we are announcing the 3DR Radio telemetry system, an open-source alternative to XBee telemetry set-ups, with superior performance, great range and a much lower price (half the price of the equivalent Xbee kit).
This is a 2-way, half-duplex wireless communication system with a standard TTL UART interface, based on HopeRF's HM-TRP data link modules, and custom firmware that improves upon the module's original features and performance.
The SiK firmware includes a bootloader that permits radio firmware updates over the serial interface, and radio firmware with configurable parameters. Updates and configuration are fully supported in the APM Mission Planner (press control-A to bring up the window below), and also possible through AT commands.
From the wiki:
Kit price is $74.99:
Individual radios are $35.99 (USB) and $31.99 (pins):
Kits and radios are available for purchase today, and they will start shipping next week.
Coming soon: a 3DR Radio XBee footprint adapter for both frequencies, compatible with our USB XBee adapter and Sparkfun's XBee Explorer boards.
We will also be releasing a version of the radios on both frequencies with an Xbee-compatible footprint, so you already have Xbee adapters, you can use them.
We hope you enjoy using these radios as much as we have during development, the simpler hardware and configuration tools compared to XBee provide a much smoother experience. We look forward to hearing your comments!
Huge thanks to the developers who made this happen: Team leaders Andrew Tridgell and Mike Smith along with Michael Oborne, Seppo Saario, Marco Robustini and others.
