MicoAir405v2 Flight Controller
The MicoAir405v2 is a flight controller produced by MicoAir.
Features
- STM32F405 microcontroller
- BMI088 IMU
- SPL06 barometer
- AT7456E OSD
- 9V 3A BEC; 5V 3A BEC
- SDCard
- 6 UARTs
- 10 PWM outputs
- 1 SWD
Physical
UART Mapping
- SERIAL0 -> USB
- SERIAL1 -> UART1 (DMA-enabled)
- SERIAL2 -> UART2 (DJI - VTX, TX only is DMA Enabled)
- SERIAL3 -> UART3 (GPS)
- SERIAL4 -> UART4 (TX only is DMA Enabled)
- SERIAL5 -> UART5 (ESC Telemetry)
- SERIAL6 -> UART6 (RX6 is inverted from SBUS pin, RX only is DMA Enabled)
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 MicoAir405v2 supports OSD using OSD_TYPE 1 (MAX7456 driver).
VTX Support
The SH1.0-6P connector supports a standard DJI HD VTX connection. Pin 1 of the connector is 9v so be careful not to connect this to a peripheral requiring 5v.
PWM Output
The MicoAir405v2 supports up to 10 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 group1 3, 4 are group 2 7,8 are group 3 9,10 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 are:
- BATT_MONITOR 4
- BATT_VOLT_PIN 10
- BATT_CURR_PIN 11
- BATT_VOLT_MULT 21.2
- BATT_CURR_SCALE 40.2
Compass
The MicoAir405v2 does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector.
Ports Connector
Loading Firmware
Initial firmware load can be done with DFU by plugging in USB with the bootloader button pressed. Then you should load the "with_bl.hex" firmware, using your favorite DFU loading tool.
Once the initial firmware is loaded you can update the firmware using any ArduPilot ground station software. Updates should be done with the "*.apj" firmware files.
