Robofusion Knowledge Hub
Practical English documentation for open-source drones, robotics telemetry, LoRa serial links and selected Meshtastic-adjacent hardware — written and maintained by the engineering team at Robofusion.
We sell and support this hardware in North America, and we use it ourselves. This hub is where we put the setup guides, reference material and field notes we wish existed in English.

Original Projects
Aircraft we design, print, build and fly ourselves — free open-source designs with complete build guides and parts kits. See the Projects section in the top menu.
- Grasshopper5 — Open-Source 5-Inch FPV Frame — the tilted-rotor printable frame with 1,800+ downloads: full build guide, firmware tilt setup, and a one-click electronics kit.
Flight Controllers
The brain of the aircraft — manuals for the MicoAir flight controllers we sell, covering ArduPilot, PX4, INAV and Betaflight.
- MicoAir H743 V2 — User Manual — the do-it-all flagship: dual IMU, Bluetooth telemetry, all four firmwares.
- MicoAir F405 V2 — User Manual — the budget long-range pick with the Bosch BMI088 IMU.
- NxtPX4 V2 — User Manual — 20×20 open-source mini board for PX4 research and VIO drones.
915 MHz Telemetry Radios
The fastest way to get a long-range telemetry link working with ArduPilot or PX4 — and to understand what the radio is actually doing.
- LR900 Telemetry Radio — User Manual — specs, model differences, interfaces and all configurable parameters.
- ArduPilot — Telemetry Setup Guide — wiring, parameters and a connection walkthrough in Mission Planner, with troubleshooting.
- PX4 — Telemetry Setup Guide — MAVLink and serial setup, plus automatic and manual connection in QGroundControl.
- CP2102 Driver Installation (Windows) — the one-time driver step before a radio shows up as a COM port.
WiFi Telemetry
Wireless flight-controller tuning and multi-drone networking over dual-band WiFi 6.
- MicoAir WiFi Link — User Manual — specs, AP/STA/BLE modes, wiring, web configuration and the full AT command reference.
- MicoAir WiFi Link — Multi-Drone Networking Tutorial — one ground station, many aircraft: STA-mode setup for swarm and light-show fleets.
2.4 GHz Telemetry & RC
Long-range 2.4 GHz LoRa links — data only, or control and data combined.
- LR24 2.4 GHz Telemetry Radio — User Manual — LR24-F / P / F-Mini model guide, full parameter reference, and how to choose between 915 MHz and 2.4 GHz.
- TRS — RC + Telemetry Combo User Manual — one 2.4 GHz link for both stick control and MAVLink telemetry, with Bluetooth ground station on Android.
Optical Flow & Range Sensors
GPS-free indoor position hold — sensor manuals plus the one configuration guide that covers all of them.
- MTF-01 — User Manual · MTF-01P — User Manual · MTF-02 / MTF-02P — User Manual · MT-01P 10m Laser Rangefinder — User Manual
- Optical Flow Setup Guide — ArduPilot / PX4 / INAV parameters, EKF source setup, and troubleshooting.
More coming
This hub is being built out. More GPS/RTK coverage and original buyer's guides and field tests are on the way — follow along in Projects, where you can also subscribe for updates.
