qmk clonecd qmk_firmware- To go to bootloader press the reset button longer than 500ms and release. Alternatively you can short the RST pin to GND, as it's wired to the reset button.

The PCBs are assembled at the fab with the production files located in the /kikit/prod/ dir.
We strongly recommend that you take a look at ebastler's symbol and footprint library for KiCAD. The Helios files are located in the "promicroish" folder with various mounting options to choose from. If you need any help integrating Helios into your keyboard PCB, please feel free to contact us.

The awesome one button reset circuit is based on the one used on the Sea-picro by joshajohnson and this very well written article by the Acheron Project.
Thank you! ❤️
