|
## 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 -> UART5 (User, DMA-enabled)
|
||
|
|
- SERIAL6 -> UART6 (RCIN, DMA-enabled)
|
||
|
|
- SERIAL7 -> UART7 (RX only, ESC Telemetry, DMA-enabled)
|
||
|
|
- SERIAL8 -> UART8 (MAVLink2, connected to on board BlueTooth module)
|
||
|
|
|
||
|
|
|
||
|
|
## RC Input
|
||
|
|
|
||
|
|
The UART6 is compatible with all ArduPilot supported receiver protocols,
|
||
|
|
|
||
|
|
* PPM is not supported.
|
||
|
|
|
||
|
|
* SBUS/DSM/SRXL connects to the RX6 pin.
|
||
|
|
|
||
|
|
* FPort requires connection to TX6 . See FPort Receivers.
|
||
|
|
|
||
|
|
* CRSF also requires a TX6 connection, in addition to RX6, and automatically provides telemetry.
|
||
|
|
|
||
|
|
* SRXL2 requires a connection to TX6 and automatically provides telemetry. Set SERIAL6_OPTIONS to “4”.
|
||
|
|
|
||
|
|
Any UART can also be used for RC system connections in ArduPilot and is compatible with all protocols except PPM. See Radio Control Systems for details.
|
||
|
|
|
||
|
|
## OSD Support
|
||
|
|
|
||
|
|
The MicoAir743v2 supports onboard OSD using OSD_TYPE 1 (MAX7456 driver). Simultaneously, DisplayPort OSD is available on the HD VTX connector, set OSD_TYPE2 = "5".
|
||
|
|
|
||
|
|
|
||
|
|
## 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 9v so be careful not to connect this to a peripheral requiring 5v.
|
||
|
|
|
||
|
|
## PWM Output
|
||
|
|
|
||
|
|
The MicoAir743v2 supports up to 11 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, 11 are Group 3;
|
||
|
|
|
||
|
|
9, 10 are Group 4;
|
||
|
|
Note: PWM11 is the "LED" pin. If this is configured for serial LED use then PWM 7 and 8 can only be used as serial LED also.
|
||
|
|
|
||
|
|
## 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 21.12
|
||
|
|
- BATT_CURR_SCALE 40.2
|
||
|
|
|
||
|
|
## Compass
|
||
|
|
|
||
|
|
The MicoAir743v2 has a built-in compass sensor (QMC5883L), and you can also attach an external compass using I2C on the SDA and SCL connector.
|
||
|
|
|
||
|
|
## BlueTooth
|
||
|
|
|
||
|
|
The MicoAir743v2 has an on board BlueTooth module connected to UART8(SERIAL8). The BlueTooth id is MicoAir743v2-xxxxxx and you can connect to it without pairing id.
|
||
|
|
|
||
|

|
## Loading Firmware
|
||
|
|
|
||
|
|
Initial firmware load can be done with DFU by plugging in USB with the bootloader button pressed. Then you should load the "XXXX_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.
