## 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.
