## Pinout

|
## UART Mapping
|
||
|
|
|
||
|
|
The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the
|
||
|
|
receive pin for UARTn. The Tn pin is the transmit pin for UARTn.
|
||
|
|
|Name|Pin|Function|
|
||
|
|
|:-|:-|:-|
|
||
|
|
|SERIAL0|COMPUTER|USB|
|
||
|
|
|SERIAL1|RX1/TX1|UART1 (DJI connector, DMA-enabled)|
|
||
|
|
|SERIAL2|TX2/RX2|UART2 (RX, DMA-enabled)|
|
||
|
|
|SERIAL3|TX3/RX3|UART3 (DMA-enabled)|
|
||
|
|
|SERIAL4|TX4/RX4|UART4 (GPS, DMA-enabled)|
|
||
|
|
|SERIAL6|TX6/RX6|UART6|
|
||
|
|
|SERIAL7|TX7/RX7|UART7|
|
||
|
|
|SERIAL8|TX8/RX8|UART8 (ESC Telemetry)|
|
||
|
|
|
||
|
|
## RC Input
|
||
|
|
|
||
|
|
RC input is configured on the (UART2_RX/UART2_TX) pins which forms part of the DJI connector. It supports all serial RC protocols.
|
||
|
|
|
||
|
|
## OSD Support
|
||
|
|
|
||
|
|
The BLITZ Wing H743 supports OSD using OSD_TYPE 1 (MAX7456 driver). Simultaneously, DisplayPort HD OSD is enabled by default and available on the HD VTX connector.
|
||
|
|
|
||
|
|
## PWM Output
|
||
|
|
|
||
|
|
The BLITZ Wing H743 has 13 PWM outputs. The first 8 outputs support bi-directional DShot and DShot, as well as all PWM types. Outputs 9-10 support DShot, as well as all PWM types and outputs 11-12 only support PWM.
|
||
|
|
|
||
|
|
The PWM are in in five groups:
|
||
|
|
|
||
|
|
- PWM 1-2 in group1
|
||
|
|
- PWM 3-6 in group2
|
||
|
|
- PWM 7-10 in group3
|
||
|
|
- PWM 11-12 in group4
|
||
|
|
- PWM 13 in group5
|
||
|
|
|
||
|
|
Channels within the same group need to use the same output rate. If
|
||
|
|
any channel in a group uses DShot then all channels in the group need
|
||
|
|
to use DShot.
|
||
|
|
|
||
|
|
## Video Power Control
|
||
|
|
|
||
|
|
The 9V video power can be turned off/on using GPIO 81 which is already assigned by default to RELAY2. This relay can be controlled either from the GCS or using a transmitter channel (See :ref:`common-auxiliary-functions`)
|
||
|
|
|
||
|
|
## Analog Airspeed Input
|
||
|
|
|
||
|
|
The analog airspeed pin is "4"
|
||
|
|
|
||
|
|
## Battery Monitoring
|
||
|
|
|
||
|
|
The board has a built-in voltage sensor and current sensor. The voltage sensor can handle up to 8S
|
||
|
|
LiPo batteries.
|
||
|
|
|
||
|
|
The correct battery setting parameters are:
|
||
|
|
|
||
|
|
- BATT_MONITOR 4
|
||
|
|
- BATT_VOLT_PIN 10
|
||
|
|
- BATT_VOLT_MULT 11
|
||
|
|
- BATT_CURR_PIN 11
|
||
|
|
- BATT_CURR_MULT 50
|
||
|
|
|
||
|
|
These are set by default in the firmware and shouldn't need to be adjusted
|
||
|
|
|
||
|
|
## Compass
|
||
|
|
|
||
|
|
The BLITZ Wing H743 does not have a builtin compass, but you can attach an external compass to I2C pins.
|
||
|
|
|
||
|
|
## 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 favourite 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.
