# MicoAir405v2 Flight Controller
|
||
|
|
|
||
|
|
The MicoAir405v2 is a flight controller produced by [MicoAir](http://micoair.com/).
|
||
|
|
|
||
|
|

|
|
## Physical
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## 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 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.
