IMU default is BMI270 (CS: PA15, bus SPI2); board also supports BMI088 (Accel CS: PD4, Gyro CS: PD5) depending on version.
Total 9 serial ports available: 8 hardware UART + 1 USB VCP.
UART6 (PC6/PC7) typically used for RC input; includes inverter circuit for SBUS controlled by pin PD0.
10 Motor/PWM outputs (M1–M10); channels M1, M3, M5 support DShot Bidirectional (read ESC telemetry via signal).
I2C2 is the internal bus for Baro/Mag (with onboard pull-ups); I2C1 is for external peripherals via connector.
MicroSD card slot (SDMMC 4-bit interface) for Blackbox/flight log recording.
Board is compatible with multiple flight controller firmware (ArduPilot, INAV, Betaflight...); specific function assignments for each UART, motor, LED depend on the firmware and configuration loaded.
