Touch button tester
TimGoll/pcb_touch_test
For an upcoming project I wanted to test how to implement PCB touch pads. The easiest solution that I could find was to use the TTP223 IC. All in all the design was pretty easy and straightforward.

Atmega isp
TimGoll/pcb_atmega328pb
The board's design is heavily based on the design of the Arduino Uno. All the USB communication stuff was removed. The board is therefore reduced to its bare minimum.
