SLIM V4 Flight Controller with Built-in OSD MicroSD for FPV RC Model Fixed-Wing Drone F7 STM32H743 Flight Stack

SLIM V4 Flight Controller with Built-in OSD MicroSD for FPV RC Model Fixed-Wing Drone F7 STM32H743 Flight Stack Description

H743 SLIM V4 is a powerful FPV flight controller designed for RC model multicopters and fixed‑wing drones. Featuring the advanced STM32H743 CPU, it delivers fast processing, smooth flight performance and reliable control for freestyle, racing and long-range builds.
Built-in OSD allows you to display critical flight data directly in your FPV goggles or monitor, including voltage, current, flight and more. The onboard MicroSD card slot supports high-capacity cards for convenient flight log recording, helping you fine-tune PID settings and analyze flight performance.
The SLIM V4 form factor offers a narrow and layout ideal for tight frames and modern stack builds. Its optimized PCB design improves heat dissipation and signal integrity, while still maintaining full-size solder pads and clearly labeled for easy wiring and maintenance.
This H743 flight controller is suitable for 5-inch racing quads, freestyle drones, long-range cruisers and FPV wings. It supports popular firmware such as Betaflight and INAV (subject to firmware availability), multiple serial , receiver and VTX, as well as PWM outputs for multirotor and fixed‑wing configurations.
Multiple UARTs, I2C, SPI and GPIO pins are available for connecting , compass, barometer, digital VTX, receiver, telemetry radio and other peripherals. The board is designed to work seamlessly with modern ESCs and PDBs, supporting current and voltage sensing, audio, LED strips and buzzer.
