Quentorres

Go to https://academany.fabcloud.io/fabacademy/2024/bootcamp-instructors/quentorres/
have a quick read and decide which board you want to mill.
I decided to do the second variant.
You will have to generate the pngs for milling with KiCAD.
Go to https://gitlab.fabcloud.org/pub/programmers/quentorres
Clone the repo to your harddisk: navigate with Explorer to the folder you want to use
rightclick and choose "git bash

Clone the whole repo:

git clone git@gitlab.fabcloud.org:pub/programmers/quentorres.git

Open KiCAD and open quentorresaurus/PCB/quentorres_v2.kikad.pcb
Go to File --> Plot
Choose the following layers:
F.CU
Edge.Cuts
and save them as pdf

Import the pdfs in Inkscape and Export them with the right colors as png with 1000dpi (tutorial still to come)

Mill them and solder them.

Step 1: open the Arduino Program under
File --> Preferences --> Additional boards manager urls
enter
https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

In Arduino IDE download the "Pico" board: Tools --> Board --> Board Manager Search for "Pico" and install the Raspberry Pi Pico/RP2040
