v2.0 - "kajetanless" white PCB

#1: Programming header J6 has non-standard layout

Use a custom cable.

#2: R1 reset line resistor is pull-down

R1 footprint shall not be populated, and an equivalent resistor should be put in a pull-up configuration between reset line and ground.

Sensible place for that is between one C2 leg and reset line going next to it to J6 programming header.

v2.1 - "pulled-up" green PCB

Errata #2 fixed.
