3DR 500mW 915MHz Radio Telemetry Kit for APM Pixhawk Multiwii

The default baud rate for radio telemetry is 57600 instead of 115200. Choose the right COM port, don’t choose AUTO These products are DIY products, if any questions, such as technical problems, please let us know, we are happy to provide you with the best service, thank you.
Features:
I preprogram these radios to the correct bod rate so you can just connect them to your quadrino and start changing PIDs on the fly.
It’s available in 915Mhz; and in the following configurations: serial board (for the air) and USB (for the ground).
The radio 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 modules’ original features and performance.
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 AT commands.
