3DR SiK Telemetry Radio - Long Range 915MHz Kit with 2x General Purpose 2dBi Antennas
by 3DR

Product Description

The 3DR SiK Telemetry Radio - Long Range 915MHz Kit is an advanced UAV communication system redesigned from the classic 3DR SiK radio. This upgraded module provides premium features such as true diversity and extended range, specifically tailored to enable Beyond Visual Line of Sight (BVLOS) operative capacity in a highly compact, power-efficient package. This specific kit comes equipped with two 2dBi General Purpose Antennas and operates on the 915MHz frequency band.

Built around open-source firmware developed for the standard MAVLink protocol, the radio integrates seamlessly with major open-source flight stacks and ground station software, including Mission Planner and QGroundControl (QGC). This radio kit utilizes interchangeable air and ground modules—meaning any unit can act as the vehicle or ground station transceiver. With features such as Frequency Hopping Spread Spectrum (FHSS), Adaptive Time Division Multiplexing (TDM), and built-in error correcting code, you can rely on robust, uninterrupted data links over several kilometers.

Note: This specific configuration includes the General Purpose Antennas and does NOT include an FTDI adapter.

Key Features:

• BVLOS Ready: High transmit power (up to 29dBm) and true diversity enable long-range missions and highly reliable communication links.

• Open Source Firmware: Fully compatible with standard MAVLink protocols, Mission Planner, and QGC. Supports AT/RT commands for local and remote radio configuration.

• Advanced Signal Routing: Features Frequency Hopping Spread Spectrum (FHSS) and Adaptive Time Division Multiplexing (TDM) to maintain a rock-solid link.

• Built-in Error Correction: Can automatically correct up to 25% of data bit errors, ensuring critical telemetry data is never lost.

• Interchangeable Modules: Each unit functions seamlessly as either an Air or Ground module.

• Status Indication: Onboard Red and Green LEDs quickly convey link status, data transmission, and firmware update modes.
