## 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 (TELEM)|
|
|||
|
|
|SERIAL2|TX2/RX2|UART2 (TELEM)|
|
|||
|
|
|SERIAL3|TX3/RX3|UART3 (RC Input/Output)|
|
|||
|
|
|SERIAL4|TX4/RX4|UART4|
|
|||
|
|
|SERIAL5|TX5/RX5|UART5|
|
|||
|
|
|SERIAL6|TX6/RX6|UART6 (GPS)|
|
|||
|
|
|SERIAL7|TX7/RX7|UART7|
|
|||
|
|
|
|||
|
|
UART3 supports RX and TX DMA. UART1, UART2, UART4, and UART6 supports TX DMA. UART5 and UART7 do not support DMA.
|
|||
|
|
|
|||
|
|
## RC Input
|
|||
|
|
|
|||
|
|
RC input is configured on the UART3, which supports serial RC protocols. This board does not support PPM.
|
|||
|
|
|
|||
|
|
## OSD Support
|
|||
|
|
|
|||
|
|
The GOKU GN 745 AIO supports OSD using OSD_TYPE 1 (MAX7456 driver).
|
|||
|
|
|
|||
|
|
## PWM Output
|
|||
|
|
|
|||
|
|
The GOKU GN 745 AIO supports up to 8 PWM outputs. The pads for motor output ESC1 to ESC4 on the above diagram are the first 4 outputs, there are four additional pads for PWM 5-8. All 8 outputs support DShot as well as all PWM types.
|
|||
|
|
|
|||
|
|
The PWM are in 5 groups:
|
|||
|
|
|
|||
|
|
PWM 6: Group 1
|
|||
|
|
PWM 1-2 and 7-8: Group 2
|
|||
|
|
LED: Group 3
|
|||
|
|
PWM: Group 4
|
|||
|
|
PWM 3-4: Group 5
|
|||
|
|
|
|||
|
|
|
|||
|
|
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. PWM 1-4 support bidirectional dshot.
|
|||
|
|
|
|||
|
|
## Battery Monitoring
|
|||
|
|
|
|||
|
|
The board has a builtin voltage sensor. The voltage sensor can handle 2S to 6S
|
|||
|
|
LiPo batteries.
|
|||
|
|
|
|||
|
|
The correct battery setting parameters are:
|
|||
|
|
|
|||
|
|
- BATT_MONITOR 4
|
|||
|
|
- BATT_VOLT_PIN 12
|
|||
|
|
- BATT_VOLT_MULT around 10.9
|
|||
|
|
- BATT_CURR_PIN 13
|
|||
|
|
- BATT_CURR_MULT around 28.5
|
|||
|
|
|
|||
|
|
These are set by default in the firmware and shouldn't need to be adjusted
|
|||
|
|
|
|||
|
|
## Compass
|
|||
|
|
|
|||
|
|
The GOKU GN 745 AIO does not have a builtin compass but it does have an external I2C connector.
|
|||
|
|
|
|||
|
|
## NeoPixel LED
|
|||
|
|
|
|||
|
|
The board includes a NeoPixel LED pad.
|
|||
|
|
|
|||
|
|
## Loading Firmware (you will need to compile your own 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.
