MicoAir F405 Mini Flight Controller Board 20x20mm & Bluejay 30A 4in1 ESC with full port enable and OSD built-in, supports Betaflight/INAV/ Ardupilot & DJI O3 Air Unit FPV
Specifications MCU: STM32F405RGT6, 168MHz, 1MB Flash IMU: BMI270 Baro: DPS310 OSD: AT7456E MicroSD Card Slot 6x UART 9x PWM 1x I2C 1x SWD 2x ADC (VBAT, Current) USB Type-C BEC 5V 2.5A output (for controller, receiver, GPS, optical flow or other devices) BEC 9V 2.5A output (for video transmitter, camera) UART Mapping SERIAL0 -> USB SERIAL1 -> UART1 (DMA-enabled) SERIAL2 -> UART2 (DJI-VTX, DMA-enabled) SERIAL3 -> UART3 (GPS) SERIAL4 -> UART4 (DMA-enabled) SERIAL5 -> UART5 (ESC Telemetry) SERIAL6 -> UART6 (RX6 is inverted from SBUS pin, no DMA on TX6) RC Input The default RC input is configured on the UART6_RX inverted from the SBUS pin. Other RC protocols should be applied at other UART port such as UART1 or UART4, and set the protocol to receive RC data: SERIALn_PROTOCOL=23 and change SERIAL6_Protocol to something other than ’23’ OSD Support The MicoAir405Mini supports OSD using OSD_TYPE 1 (MAX7456 driver). VTX Support The SH1.0-6P connector supports a DJI O3 Air Unit connection. Pin 1 of the connector is 9v so be careful not to connect this to a peripheral requiring 5v. PWM Output The MicoAir405Mini supports up to 9 PWM outputs. Channels 1-8 support DShot. Channels 1-4 support bi-directional DShot. PWM outputsare grouped and every group must use the same output protocol: 1,2,5,6 are group 1 3, 4 are group 2 7,8 are group 3 9 are in group 4 Battery Monitoring The board has a internal voltage sensor and connections on the ESC connector for an external current sensor input. The voltage sensor can handle up to 6S LiPo batteries. The default battery parameters(for Ardupilot) are: BATT_VOLT_PIN 10 BATT_CURR_PIN 11 BATT_VOLT_MULT 21.2 BATT_CURR_SCALE 40.2 Compass The MicoAir405Mini does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector. Physical Mounting: 20 x 20mm, Φ3.5mm Dimensions: 30 x 30 x 8 mm Weight: 6g
