Overview
A Holybro 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). The radio uses open source
firmware which has been specially designed to work well with MAVLink packets and to be
integrated with the Mission Planner, Copter, Rover and Plane.
The main features of the Holybro Radio are listed below:
Receiver sensitivity to -121 dBm
Transmit power up to 20dBm (100mW)
Transparent serial link
Air data rates up to 250kbps
MAVLink protocol framing and status reporting
Frequency hopping spread spectrum (FHSS)
Adaptive time division multiplexing (TDM)
Support for LBT and AFA
Configurable duty cycle
Built-in error correcting code (can correct up to 25% data bit errors)
AT commands for radio configuration
RT commands for remote radio configuration
GFSK modulation
The FT230X is a USB to serial UART interface data transfer chip. It gives the radio the ability to
connect to a USB host device.
