Indigenous Autopilot + ESAD Systems

Indigenous flight-control hardware with integrated safety architecture.

AutoPilot Flight Controller & ESAD pairs Walnut, a compact 8-layer autopilot PCB, with an ultra-compact safety module for UAV integration. The board supports multi-protocol interfaces, integrated battery sensing, and firmware integration with ArduPilot and PX4; ESAD adds micro-controller validation logic and dual-gated initiation control through standard I/O rails.
