RF-Engineered Flight Controller for Professional UAV Systems
Built around a dual-MCU architecture, triple-redundant power system, and a 6-layer RF-conscious PCB designed for demanding autonomous platforms.
PX4-compatible • USB-C • Dual IMU • Triple Power Redundancy
Engineering decisions that separate ARIADNE from commodity flight controllers
Signal integrity principles uncommon in flight controllers
Lower noise floor means cleaner sensor data, which translates to more stable attitude estimation and tighter position hold.
Independent brick, servo rail, and USB power inputs
Your vehicle maintains control authority even when a power rail fails — critical for operations over populated areas or expensive payloads.
STM32F7 flight processor + dedicated STM32F1 I/O processor
If the flight management unit encounters a fault, the IO processor can independently execute failsafe procedures — motor shutdown or return-to-land.
Built for real UAV systems, not bench demos
Every connector and bus is placed for actual integration scenarios — no adapter boards, no pin-header soldering, no compromise wiring.
Two processors, clear responsibility boundaries

Connected via USART6 · Independent reset domains · Separate power regulation
Design decisions that matter in the field
Each IMU operates on a dedicated SPI bus. A fault on one sensor path cannot propagate to the other — true electrical isolation, not just software redundancy.
Modern connector with reversible insertion and robust mechanical retention. Panel-mount compatible for enclosed airframes where access is limited.
JST-GH connectors across all interfaces provide locking engagement rated for vibration environments — the same standard used throughout the PX4 ecosystem.
4-bit SDIO interface provides sustained write throughput for high-rate logging. No data loss during aggressive maneuvers or rapid attitude changes.
