The board is supported with Cleanflight and Betaflight firmware and uses the more-powerful STM32F3 microcontroller, with 256K bytes of flash memory, 3 hardware serial ports plus USB, and a floating point math coprocessor for fast control looptimes. Board include PDB support to hexa, built-in LC filter for FPV video signal. Please use Mission Planner 1.3.76 or QGroundControl v4.2.0 or newer if firmware upload is required.Designed for acro and FPV Micro and Mini racing indoor with SUB-130 size, this board provides the most-needed features in a compact and practical form factor, on a 27x27mm board compatible with 20mm mounting hole spacing. Older firmware without SI1060 chip support is not compatible. The current batch of Sik Telemtry Radio uses the SI1060 chip (previously SI1000) shipped with updated firmware.

The radios can be either 915Mhz or 433Mhz and you should purchase the model which is appropriate for your country/region. It uses open source firmware which has been specially designed to work well with MAVLink packets and to be integrated with the Mission Planner, Ardupilot, QGroundControl, PX4 Autopilot. This radio is plug-n-play all Pixhawk Standard and other Flight Controller, providing the easiest ways to setup a telemetry connection between your Autopilot and a ground station. This Holybro SiK Telemetry Radio is a small, light and inexpensive open source radio platform that typically allows ranges of better than 300m “out of the box” (the range can be extended to several kilometres with the use of a patch antenna on the ground).
