Oh no. When the case LEDs are switched off, the input pin will receive 12V, which is out of spec for the STM32. We'll need a driver. |
Avoids putting 12V on STM32 I/O pin.
Moved power output header. Change TO-92 BJTs to SOT-23.
Lots of parts just changed their component designator. I had to patch up the PCB manually, but now it imports from the schematic OK. Also adds two PSU rails for the RTC (so you can pick DS1307 which is a 5V part, or MCP7940N which is a 3.3V part).

No longer used with Kicad 6
Also moved a wire on the IO page, and amended some doc comments in the schematic. Notably the Power Input limit is now 30V because of the Zener on the control line.

Case LEDs are now driven by VDC and 1K. Allows higher Vf LEDs to work.
Added 6mm buttons.
Fiddled with tracking around CODEC.
Change I2S pin ordering.
