AirBrain H743.
Any firmware. Every mission.
Compact 20×20 flight controller built around the STM32H7. Synchronised with an ICM-42688-P IMU for low-latency, low-noise flight on Betaflight, ArduPilot, and PX4.
ex VAT. Retail varies by reseller and region.
3stacks
Upstream target in Betaflight, ArduPilot, and PX4. No vendor lock-in.
EU + US + JPBOM sourcing
Belgian assembly. Per-line supplier breakdown on request under NDA.
MCUdrives sample timing
STM32H7 clock drives the ICM-42688-P. No software interpolation between sample and PID.
3 to 10S(10 to 42 V)
Same board across compact race builds and heavy-lift cinema rigs.
Race cine FPV at Mugello
Mugello chase footage flown at 250 km/h on AirBrain H743 with stock Betaflight. Telemetry and blackbox logs were clean across the whole session.
Footage: AeroplayfilmsThe decisions that show up in flight logs.
Clock-synced IMU
The STM32H7 clock drives the ICM-42688-P sample timing directly, so there is no software interpolation between sensor read and the PID loop. The gain budget is wider before stick filtering needs to step in.
Isolated power rails
Sensor rails are physically separated from motor rails on the layout. Commutation noise from the ESCs does not couple back into the gyro path. Blackbox logs are cleaner at sustained high throttle.
Industrial-grade BOM
Components are sourced through EU, US, and Japanese channels and the board is NDAA compliant. A per-line supplier breakdown is available on request for integrators who need to certify.
EMC tested layout
Pre-compliance EMC sweeps are run on every revision before the BOM is locked. The board is tested against ESC, VTX, and RX coexistence on a real airframe, not just on the bench.
6 platforms, one flight controller.
Cinematic FPV with predictable rates and ultra-low latency.
ArduPilot autonomy with reliable GPS + magnetometer fusion.
Survey-grade flights with PX4.
Hardware target upstream in PX4 + ArduPilot.
ArduPilot Plane on the same hardware target.
Open hardware definition; extend without forking.
Synced clocks with the IMU for ultra-low-latency control loops.
Industrial-grade gyro on isolated power rails.
LIS2MDL + DPS368. ArduPilot LIS2MDL driver upstream since 2025-11.
Drops into compact stack-ups without forcing redesign.
Wide 10 to 42 V range with 5 V at 2 A and 10 V at 2.5 A regulated outputs.
Sealed connector survives splashes, dust, and field abuse.
Hardware target merged upstream. Same board, multiple platform classes.
Procurement-grade evidence, not just a checkbox.
Covered telecommunications equipment
Restricts federal agencies from procuring covered telecommunications equipment from designated foreign vendors. UAS components fall under follow-on provisions.
Covered foreign entities for UAS
Restricts federal agencies from procuring drones or drone components from covered foreign entities and their state-controlled affiliates. Effective 2025 for new federal procurement.
DoD restricted-entity list
Annual DoD list of restricted foreign industrial entities. Federal procurement and capital-markets restrictions reference this list.
Per-line attestation for integrators
Procurement-bound integrators need to show their own supply chain. We document every BOM line with manufacturer country of origin so you can roll our posture into yours.
