|
||
|
|
|
||
|
|
The JHEMCU GSF405A is a 1-2S Whoop-style (25.5mm x 25.5mm) flight controller featuring the STM32F405OG6 MCU, 4in1 5A ESCs, BMP280 barometer, 8MB flash, and an on-board ExpressLRS 2.4GHz receiver. The board weighs 3.3g, making it suitable for small or lightweight ArduPilot builds.

## 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) - Used by the on-board ELRS receiver|
|
||
|
|
|SERIAL2|TX2/RX2|USART2 (DMA - RX2/TX2/SBUS pads|
|
||
|
|
|SERIAL3|TX3/RX3|USART3|
|
||
|
|
|SERIAL4|TX4/RX4|UART4|
|
||
|
|
|SERIAL6|TX6/RX6|USART6 (DMA) - Telemetry|
|
||
|
|
|
||
|
|
## RC Input
|
||
|
|
|
||
|
|
RC input is configured on SERIAL2 (USART2), which is available on the RX2, TX2, and SBUS pads. PPM receivers are *not* supported as this input does not have a timer resource available.
|
||
|
|
*Note* A different target is available should you want to use the built-in ExpressLRS 2.4GHz receiver on USART1.
|
||
|
|
|
||
|
|
## OSD Support
|
||
|
|
|
||
|
|
The GSF405A supports OSD using OSD_TYPE 1 (MAX7456 driver).
|
||
|
|
|
||
|
|
## Motor Output
|
||
|
|
|
||
|
|
The built-in ESC is mapped to motor outputs 1-4. Bidirectional DShot is supported (requires flashing the ESC to a BLHeli_S version that supports bdshot, such as [Bluejay](esc-configurator.com)).
|
||
|
|
|
||
|
|
## Battery Monitoring
|
||
|
|
|
||
|
|
The board has a built-in voltage and current sensors.
|
||
|
|
|
||
|
|
The correct battery setting parameters are:
|
||
|
|
|
||
|
|
- BATT_MONITOR 4
|
||
|
|
- BATT_VOLT_PIN 11
|
||
|
|
- BATT_VOLT_SCALE 11
|
||
|
|
- BATT_CURR_PIN 13
|
||
|
|
- BATT_CURR_SCALE 17
|
||
|
|
|
||
|
|
These are set by default in the firmware and shouldn't need to be adjusted
|
||
|
|
|
||
|
|
## Compass
|
||
|
|
|
||
|
|
The GSF405A 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 fifth PWM 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.
