The SimpliFly SiK Telemetry Radio is a reliable wireless module for long-range data transmission in UAVs, drones and robotics. Operating on the 433MHz band, it enables stable, efficient telemetry between ground control stations and airborne systems. With 100mW of output it balances range and power efficiency for both hobbyists and professional users.
It is built on open-source SiK firmware and integrates with popular flight controllers and ground-station software. USB and serial interfaces give it plug-and-play connectivity, and setup and configuration are straightforward.
The module delivers low-latency communication that suits real-time monitoring, data logging and control, even in demanding environments.
433MHz band: chosen for long-range communication.
100mW output: a stable link with modest power draw.
Open-source SiK firmware: widely supported and configurable.
Plug-and-play setup: USB and serial interfaces with easy configuration.
Real-time data: supports live monitoring and control.
Built for UAVs and robotics: drones, UAVs and other robotic systems.
SiK radios are small serial-to-radio modems. Data written to the serial or USB port is sent over the air and appears at the serial port of the paired radio. In a drone, one radio connects to the flight controller and the other to the ground station.
Because the firmware is open source and MAVLink compatible, ground-station software can connect as if it were plugged directly into the flight controller, while the radio handles retries and framing.

Robotics projects that need a wireless serial link
Long-range drone and UAV operations in line of sight
The radio offers UART and USB interfaces, MAVLink-compatible communication, operating voltage of 5V (USB) or 3.3V logic and an operating temperature range of -10 C to +60 C. Data rates go up to 250kbps and the listing quotes a range of up to several kilometers in line of sight.
Pair it with a second radio at the same frequency and settings, and check the rules for 433MHz use where you fly.
