100mW Radio Telemetry Kit 433MHz / 915MHz (Air + Ground)

A matched pair of 100mW SiK-firmware telemetry radios that gives your flight controller a two-way MAVLink link to the ground station. Watch live flight data, upload and edit missions, change parameters and trigger modes in flight on ArduPilot or PX4 aircraft — fixed-wing, VTOL or multirotor. Choose 433MHz or 915MHz to match your other radios and local frequency rules.

Key features

• Air and ground modules are identical and interchangeable — either end can sit on the aircraft or the laptop.
• Each module has a micro-USB port (CP2102 USB-serial) for the PC or tablet and a 6-pin DF13 port for the flight controller's TELEM UART.
• Frequency-hopping spread spectrum (FHSS) with adaptive time-division full-duplex link.
• Built-in error correction recovers up to 25% bit errors; MAVLink framing and link-quality (RSSI) reporting.
• Output power, air data rate and net ID are configurable from Mission Planner, QGroundControl or AT commands.
• Plug-and-play with Pixhawk, Cube and APM flight controllers — cables for both port styles are included.

Specifications

• Frequency: 433MHz or 915MHz (select variant)
• Output power: up to 100mW (20dBm), adjustable
• Receive sensitivity: down to −117dBm
• Air data rate: up to 250kbps
• Protocol: MAVLink over transparent serial, SiK firmware
• Interfaces: micro-USB + 6-pin DF13 (TX, RX, 5V, GND)
• Supply voltage: 5V
• Antenna connector: RP-SMA
• Operating temperature: −10 to 85°C
• Typical range: 1–2km line of sight with the stock antennas (more with higher-gain antennas)

In the box

• 2 × 100mW telemetry radio modules (air + ground)
• 2 × 3.5dBi antennas
• 2 × flight-controller cables (Pixhawk and APM style)

Both radios in a link must run the same frequency, net ID and air data rate — the pair ships matched. Module enclosures may vary between batches (cased or bare board); the electronics and firmware are the same.
