Capacitve human interface devices

Initial development was done using a stm32 nucleo board. The final product will have a stm32F103 micro.  I used a pre existing PCB with a similar micro to port the firmware over.  Thankfully at this point it's mostly just copy and paste.

Did the boring part and put together a BOM on digikey, as well as an order on JLC pcb.  All components should be arriving next week as of 2/28/2024.  Very excited.

Today I posted my PCB design on Reddit in order to get feedback on my layout.  I will also be working on porting the firmware to the STM32F103CBT6 micro controller, as well as component selection in order to have a working BOM.

Minor edits to PCB.  I'm going to sit on the design for a while before I send it out for fab.
