Product overview
The HAKRC 40A miniF4 Stack from Shenzhen Haike Technology Co., Ltd. combines an F405 flight controller and a BLHeli-32 40A four-in-one ESC for UAV flight control and motor control integration. Both boards have 20 * 20mm mounting-hole spacing, while their footprints differ: the controller measures 29 * 39mm and the ESC measures 44 * 44mm. Installation space therefore needs to accommodate the larger ESC board. Each board has a net weight of 6g, and both accept 2S-6S LiPo input.
The controller combines an STM32F405RET6 processor, ICM42688 IMU, integrated barometer, AT7456E OSD, 16MB black box and built-in current sensor. Its integration connections include five serial ports, F.Port, Type-C USB, external adjustable LED support and a connector for the DJI O3 Air Unit. Receiver interfaces include SBUS, ELRS, PPM, CRSF, DSMX, iBus and DSM2. Electrical ratings are 5V/2A for EC and 10V/2A for BEC. The ESC supports telemetry and the listed PWM, Oneshot, Multispot and Dshot protocols, with current ratings of 40A continuous and 45A peak.
