## 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|USART1 (DMA) - RC Input/Output |
|
||
|
|
|SERIAL2|TX2/RX2|USART2 (DMA RX only) - MAVLink2 |
|
||
|
|
|SERIAL3|TX3/RX3|USART3 (DMA TX only) - GPS1 |
|
||
|
|
|SERIAL4|TX4/RX4|UART4 (DMA TX only) - VTX |
|
||
|
|
|SERIAL6|TX6/RX6|USART6 - User |
|
||
|
|
|
||
|
|
## RC Input
|
||
|
|
|
||
|
|
SBUS input must be on SBUS pin, all others can use RX1, CRSF/ELRS/SRXL2 must also use TX pin
|
||
|
|
|
||
|
|
## OSD Support
|
||
|
|
|
||
|
|
The GSF405A supports OSD using OSD_TYPE 1 (MAX7456 driver).
|
||
|
|
|
||
|
|
## PWM Output
|
||
|
|
|
||
|
|
The JHEM_JHEF405 supports up to 9 PWM outputs (PWM9 is the serial LED output, by default). All outputs support DShot.
|
||
|
|
|
||
|
|
The PWM is in 5 groups:
|
||
|
|
|
||
|
|
* PWM 1,2,5 in group1
|
||
|
|
* PWM 3,4 in group2
|
||
|
|
* PWM 6 in group3
|
||
|
|
* PWM 7,8 in group4
|
||
|
|
* PWM 9 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 that group would need to use DShot.
|
||
|
|
|
||
|
|
## Battery Monitoring
|
||
|
|
|
||
|
|
The board has a built-in voltage and current sensors.
|
||
|
|
|
||
|
|
The correct battery setting parameters are:
|
||
|
|
|
||
|
|
- BATT_MONITOR 4
|
||
|
|
- BATT_VOLT_PIN 13
|
||
|
|
- BATT_VOLT_SCALE 11.0
|
||
|
|
- BATT_CURR_PIN 12
|
||
|
|
- BATT_CURR_SCALE 58.8
|
||
|
|
|
||
|
|
These are set by default in the firmware and shouldn't need to be adjusted
|
||
|
|
|
||
|
|
## Compass
|
||
|
|
|
||
|
|
The JHEM_JHEF405 does not have a builtin compass, but you can attach an external compass to the I2C pins.
|
||
|
|
|
||
|
|
## LED
|
||
|
|
|
||
|
|
The board includes a LED_STRIP output, which is assigned a timer and DMA. This is the PWM 9 output.
|
||
|
|
|
||
|
|
## 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.
