FrSky F405 flight controller based on STM32F405RGT6. Hardware: IIM-42688P gyro (SPI1), AT7456E OSD (SPI2), SD card (SPI3), SPL06 barometer (I2C1), 9 motor outputs, hardware SBUS inverter on UART2, LED strip on PA15. S7/S8 use TIM12 (PWM only, no DShot).

Testing checklist:
|
- Fix UART5_RX: PD12 → PD2 (only valid pin for UART5_RX on STM32F405) - Move SPI3 to PB3/PB4/PB5, freeing PC10/PC11/PC12 for UART3 and UART5_TX - Move UART3 to PC10/PC11 (was conflicting with I2C2 on PB10/PB11) - Fix UART4_RX: PC5 → PA1 (PC5 is shared with RSSI ADC) - Re-enable I2C2 on PB10/PB11 (now free after UART3 move) - Add TARGET_IO_PORTD for PD2 (UART5_RX) - Update SERIAL_PORT_COUNT to 7 (includes UART5) - Remove config.c: UART2 has both standard and hardware-inverted SBUS pads
