4-in-1 electronic speed controller built for demanding multirotor platforms. 60A continuous per channel with 80A burst, powered by four independent STSPIN32F0A processors. Supports 3S–8S LiPo, DSHOT600, bidirectional telemetry, and AM32 firmware out of the box. 8-layer PCB with polyurethane conformal coating — built to survive the field.
