# MicoAir405Mini Flight Controller
|
||
|
|
|
||
|
|
The MicoAir405Mini is a flight controller designed and produced by [MicoAir Tech.](http://micoair.com/).
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
- STM32F405 microcontroller
|
||
|
|
- BMI270 IMU
|
||
|
|
- DPS310 barometer
|
||
|
|
- AT7456E OSD
|
||
|
|
- 9V 2.5A BEC; 5V 2.5A BEC
|
||
|
|
- SDCard
|
||
|
|
- 6 UARTs
|
||
|
|
- 9 PWM outputs
|
||
|
|
|
||
|
|
## Physical
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## UART Mapping
|
||
|
|
|
||
|
|
- SERIAL0 -> USB
|
||
|
|
- SERIAL1 -> UART1 (MAVLink2, DMA-enabled)
|
||
|
|
- SERIAL2 -> UART2 (DisplayPort, TX only is DMA Enabled)
|
||
|
|
- SERIAL3 -> UART3 (GPS)
|
||
|
|
- SERIAL4 -> UART4 (MAVLink2, 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 as SBUS via the SBUS pin. Other RC protocols should be applied at a 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 onboard 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 outputs are grouped and every group must use the same output protocol:
|
||
|
|
|
||
|
|
3, 4 are Group 1;
|
||
|
|
|
||
|
|
1, 2, 5, 6 are Group 2;
|
||
|
|
|
||
|
|
7, 8 are Group 3;
|
||
|
|
|
||
|
|
9 is 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 MicoAir405Mini does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector.
|
||
|
|
|
||
|
|
## Mechanical
|
||
|
|
|
||
|
|
- Mounting: 20 x 20mm, Φ3.5mm
|
||
|
|
- Dimensions: 30 x 30 x 8 mm
|
||
|
|
- Weight: 6g
|

|
## 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.
