STM32F411CEU6 INAV Flight Controller

Custom Flight Controller (based on INAV MATEKF411TE)
This FC was designed by me and is based on the INAV MATEKF411TE firmware.

Specifications

• MCU: STM32F411CEU6
• IMU: ICM42605 / ICM42688P (interchangeable; 42688P is higher quality and more expensive)
• Barometer: BMP280
• Interfaces: SPI, I2C, UART, 6 PWM channels available
• Power: Input 5V, onboard LDO RT9193 regulates down to 3.3V.

You will need an external buck converter to step down battery voltage to 5V.

Hardware

• 2-layer PCB for the lowest possible cost.
• USB-C connector.

Firmware

• The board can be directly flashed with the Matek F411TE firmware using INAV Configurator 7.1.0.
• Note: INAV 8 no longer supports F411.

First-time Setup (fresh soldered, blank chip):

1. Hold the BOOT button
2. Plug in USB-C
3. Open INAV Configurator → Flash Firmware → Select MATEKF411TE → Load → Flash

That's it! Enjoy your flight 🚀
