Holybro 17022 SiK Telemetry Radio
Overview
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).
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. 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.
The radios can be either 915Mhz or 433Mhz and you should purchase the model
which is appropriate for your country/region.
Note:
This radio does not support firmware upload via Mission Planner 1.3.75 or
order. Please use Mission Planner 1.3.75.1 or newer if firmware upload is
needed.

LEDs Indicators Status
The radios have 2 status LEDs, one red and one green. The meanings of the different LED states are:
- Green LED blinking – searching for another radio
- Green LED solid – link is established with another radio
- Red LED flashing – transmitting data
- Red LED solid – in firmware update mode
Connecting to Pixhawk Standard Flight Controller
Use the 6 pin JST-GH connector that come with the radio to connect the radio
to your flight controller’s “Telem 1” (“Telem 2” can also be used but the
default recommendation is
“Telem1”).
Connecting to a PC or Ground Station
Connecting the radio to your Windows PC or Ground Station is as simple as
connecting the micro/type-C USB cable (both included with the radio) to your
PC/Ground Station. The necessary drivers should be installed automatically and
the radio will appear as a new “USB Serial Port” in the Windows Device Manager
under Ports (COM & LPT). The Mission Planner’s COM Port selection drop-down
should also contain the same new COM port.
