Current status: everything works fine, no  problems found!

Features:

  • STM32F405
  • ICM42688P gyroscope + accelerometer
  • Blackbox
  • OSD
  • 3-8S voltage
  • Powerful 3.5A DC converters
  • 3.3V / 5V / 10V rails
  • SCL and SDA pins for GPS
  • 6 UARTs
  • 8 motor/servo outputs
  • RX4 inverter (for SBUS)
  • SWD and SWC pins for direkt programming via bootloader (ex. ST-Link)

Size: 40/40/1,6 mm

Drill diameter: 4 mm

Drill distance: 30,5 mm (center to center)

Software flashing

At this moment, it is only available to flash the software to the board as an unofficial Betaflight target.

You can find all the needed files to configure the board in the attachments below.

  1. Make sure you have installed all the needed drivers (Zadig, ImpulseRS)
  2. Connect the board to your PC via TYPE-C cable while holding the "BOOT" button. After that, a device in DFU mode should be detected
  3. Go to "Firmware Flasher" tab and load the .hex file by clicking on the "Load Firmware [Lokal]" tab
  4. Click the "Flash Firmware" button
  5. Once the firmware flashed successfully, press the "Connect" button and go to the "CLI" tab
  6. Press "Load from file" button and select .config file

Load the commands to the CLI and reconnect the FC

PCB purchase

Starting from June 2024, you have a great opportunity of purchasing the first version of SOWA F4 flight controller for 34,90$ (1400 UAH). The PCB is produced by JLCPCB in China. Delivery is carried out from Ukraine by courier service of Nova Post within its borders, as well as in the European Union and the United States. *All profits will be used to improve this project and to develop new ones. 

 

The board comes with a set of dampfers (4pcs)

Sponsors

I would like to express my sincere gratitude to the OSHWlab Stars program for their significant assistance in funding this project as well as to JLCPCB for providing it`s manufacturing power facilities.
