|
||
|
|
|
||
|
|
The MicoAir743-AIO is a flight controller designed and produced by [MicoAir Tech](http://micoair.com/).
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
## Physical
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## UART Mapping
|
||
|
|
|
||
|
|
- SERIAL0 -> USB
|
||
|
|
- SERIAL1 -> UART1 (MAVLink2, DMA-enabled)
|
||
|
|
- SERIAL2 -> UART2 (DisplayPort, DMA-enabled)
|
||
|
|
- SERIAL3 -> UART3 (GPS, DMA-enabled)
|
||
|
|
- SERIAL4 -> UART4 (MAVLink2, DMA-enabled)
|
||
|
|
- SERIAL5 -> UART6 (RCIN, DMA-enabled)
|
||
|
|
- SERIAL6 -> UART7 (RX only, ESC Telemetry, DMA-enabled)
|
||
|
|
- SERIAL7 -> UART8 (User, DMA-enabled)
|
||
|
|
|
||
|
|
## RC Input
|
||
|
|
|
||
|
|
The default RC input is configured on the UART6. The SBus input on the HD VTX connector is tied to RX6.
|
||
|
|
|
||
|
|
|
||
|
|
## VTX Support
|
||
|
|
|
||
|
|
The SH1.0-6P connector supports a DJI Air Unit / HD VTX connection. Protocol defaults to DisplayPort. Pin 1 of the connector is 12v so be careful not to connect this to a peripheral requiring 5v.
|
||
|
|
|
||
|
|
## PWM Output
|
||
|
|
|
||
|
|
The MicoAir743-AIO supports up to 9 PWM outputs.
|
||
|
|
|
||
|
|
All the channels support DShot.
|
||
|
|
|
||
|
|
Channels 1-8 support bi-directional DShot.
|
||
|
|
|
||
|
|
PWM outputs are grouped and every group must use the same output protocol:
|
||
|
|
|
||
|
|
1, 2, 3, 4 are Group 1;
|
||
|
|
|
||
|
|
5, 6 are Group 2;
|
||
|
|
|
||
|
|
7, 8, 9 are Group 3;
|
||
|
|
|
||
|
|
PWM1-4 are internally tied to the 4-in-1 ESC. PWM 9 is labelled as LED output on the board.
|
||
|
|
## Battery Monitoring
|
||
|
|
|
||
|
|
The board has internal voltage sensor and current sensor for battery.
|
||
|
|
The voltage input should be 3~6S 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 14.14
|
||
|
|
|
||
|
|
## Compass
|
||
|
|
|
||
|
|
The MicoAir743-AIO does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector.
|
||
|
|
|
||
|
|
## Mechanical
|
||
|
|
|
||
|
|

|
||
|
|
- Dimensions: 36 x 36 x 8 mm
|
||
|
|

|
|
## 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.
