This is the control board for my custom power supply design. No 3rd party modules dependencies - all on a single board and NRF52832 based. For touch sensing support I used Cypress Semiconductor IC's which are best in class for this purpose.
Note:
Initial design was made using EasyEDA but was ported to KiCAD with the help of the easyeda2kicad awesome tool. Only the PCB was ported as exporting schematics is not supported yet by the tool. Some re-touches were needed also but everything should be in place.
Added BOM in JLCPCB/LCSC format. All components can be sourced from LCSC if desired.
** Tested and it works! **
Revisions:
- 0.1 - initial design
- 0.2 - fixed/optimized some traces
- 0.3 - hatched ground plane support
