HOW WE BUILD — TECHNICAL RESOURCES
These packages are contract development: you receive schematics, PCB data, hwdef.dat and firmware for your board. For an off-the-shelf board see the KURAGE FC hardware lineup. The engineering behind every package is documented publicly (Japanese, with English available on note):
- FC5 — Requirements for an ArduPilot-compatible board: hwdef.dat structure and minimum hardware
- FC4 — STM32H7 selection: H743 / H745 / H753 / H7A3
- FC2 — UAV control architecture: attitude, position and mission layers
- ESC1 — How an ESC drives a brushless motor
- SITL — Reducing real-flight tests with ArduPilot simulation
- Release note — KURAGE FC v1.0.0 (triple IMU, encrypted FHSS)
