Product overview
The GEPRC GEP-F405-8S Flight Controller provides flight-control electronics for integration into a UAV assembly. It combines an STM32F405 processor with an ICM42688-P IMU using SPI, an integrated barometer and 16M onboard Blackbox storage. Connections include eight motor outputs designated M1-M8, six UARTs and a Type-C USB interface. For video integration, it supports direct plugging into a DJI Air Unit and includes BetaFlight OSD with an AT7456E chip. Its firmware target is GEPRCF405_8S.
The 37x37mm board weighs 8.3g and uses a 30.5×30.5mm mounting pattern. Mounting holes are φ4mm, reducing to φ3mm with silicone shock-absorbing rings installed. Power input is specified for 3-8S LiPo batteries, with independent 5V@3A and 12V@3A BEC supplies and an integrated LC filter. The supplied component package contains one controller, DJI Air Unit and flight controller adapter cables, one camera connection cable, two SH1.0 4-pin silicone cables, four nylon nuts and four silicone grommets.
