SiK Telemetry Radio V3
Quick Start Guide
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.
