Overview
The HAKRC F405 Lite Flight Controller is a compact, high-performance FC designed for FPV drones requiring precision, reliability, and flexible I/O. Built with a 4-layer 1oz copper PCB and resin plug-hole technology, this board ensures strong anti-interference capability and durability under high temperatures with industrial-grade LDOs and Japanese Murata capacitors.
Powered by the STM32F405RGT6 processor and ICM42688 gyro, the controller includes 16MB blackbox storage, an integrated barometer, and AT7456E OSD for real-time flight data. It supports up to 8 motor outputs, dual camera switching (CAM1/CAM2 via USER1), and Bluetooth module expansion. Solder-free push-in connectors simplify installation for all levels of builders.
