Description

This mini telemetry kit utilizes the open-source 3DR Radio firmware, providing a reliable two-way communication channel between your ground station and UAV. It operates on the 915MHz ISM band, employing frequency-hopping spread spectrum (FHSS) and adaptive TDM to maintain a stable link even in RF-noisy environments. The system is built around the Si1000 and Si4432 wireless microcontroller modules, delivering a receive sensitivity of -117 dBm.

The kit includes two identical modules, eliminating the distinction between air and ground ends. Each module features a Micro-USB port and a 6-pin DF13 serial connector (UART interface), allowing for straightforward wiring to compatible flight controllers. The enclosed design protects the internal components and includes a complete wiring harness for immediate integration into your drone build.

Key Features

  • 915MHz FHSS Telemetry: Operates on a license-free band with frequency-hopping technology for enhanced interference resistance and a demonstrated range of several kilometers.
  • MAVLink Protocol & Open-Source Firmware: Fully compatible with Mission Planner, APM Planner, and other GCS software using the standard MAVLink framing and status reporting.
  • Interchangeable Module Design: Both included modules are identical, simplifying spares management and allowing flexible use as either air or ground units.
  • High-Performance RF Core: Based on Silicon Labs Si1000 and Si4432 chipsets, offering an air data rate of 250kbps and robust error correction.
  • User-Upgradable Firmware: Integrated CP2102 USB-to-TTL chip enables easy firmware updates via Micro-USB without additional tools.
  • Complete & Protected Kit: Modules are housed in independent cases with pre-assembled cables (APM/Pixhawk compatible), improving reliability and installation aesthetics.

Applications

  • Long-range telemetry and mission planning for APM or Pixhawk-based fixed-wing UAVs and multirotors.
  • Real-time flight data monitoring and parameter tuning for autonomous drone platforms running ArduPilot or PX4.
  • Providing a robust backup telemetry link for FPV racing or freestyle drones equipped with compatible flight controllers.
  • Educational and development projects requiring open-source, configurable MAVLink communication hardware.

Frequently Asked Questions

What flight controllers is this telemetry kit compatible with?

This kit is compatible with any flight controller that supports the MAVLink protocol over a UART interface, including APM 2.x, Pixhawk series, Pixhawk 2/4/6, PX4, and MultiWii (MWC) boards. It is configured for use with ground control software like Mission Planner and APM Planner.

How do I update the firmware on these modules?

Firmware updates can be performed via the Micro-USB port on each module. The integrated CP2102 USB-to-TTL chip allows you to connect directly to a computer. You will need the appropriate open-source 3DR Radio firmware files and a flashing utility, but no additional hardware tools are required.

What is the maximum range I can expect with this kit?

Under ideal line-of-sight conditions with the included 3.5 dBi omnidirectional antennas, a range of several kilometers is achievable. The actual range is influenced by output power (100mW), antenna placement, local RF interference, and physical obstructions. The frequency-hopping spread spectrum (FHSS) helps maintain a stable link in noisy environments.

Are the air and ground modules different?

No, the two modules included in the kit are physically and functionally identical. This interchangeable design means either module can be used as the air unit or ground unit, simplifying setup and providing a ready spare if needed.

What cables and connectors are included?

The kit includes two pre-wired cables with DF13 6-pin connectors on one end, designed for direct connection to common APM and Pixhawk flight controller telemetry ports. Each module also has a Micro-USB port for power, configuration, and firmware updates. Note that a USB OTG cable for connecting to mobile devices is not included.

Package Includes

  • 2x 915MHz Telemetry Modules (with cases)
  • 2x APM/Pixhawk Connection Cables
  • 2x 3.5 dBi Omnidirectional Antennas
