The main goal of this project is to create a free open-source flight controller you can use for your personal needs.

29.09.2024 --> ! Important update !

I have figured out that OSD doesn`t work correctly. 

Due to the lack of time nowadays, I will try to solve the problem as soon as I have a chance.

13.12.2024 --> About the OSD: When I connect a camera I receive the following video output (see the photo). I tried to change OSD settings and fonts in Betaflight but that didn`t help. Last time I tried to replace the AT7456E chip on my board from an old Omnibus F3 FC and then everything worked perfectly. After that I placed other chips from LCSC to my board and then it didn`t work again. That`s why I only suspect that the chips should be somehow pre-programmed.
If somebody knows or has any ideas of how to fix this problem I will be very gratefull if you contact me. Thanks.

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
