The project gets the cards from a specific list:

https://developer.atlassian.com/cloud/trello/rest/api-group-lists/#api-lists-id-cards-get

Of course this includes requesting an API key for Trello and figuring out the ID of your selected list.

The response includes all data. I limited the card count for 10 to my list and since the API response is pretty chatty, I would recommend too to avoid running out of memory.

Set the Wi-Fi SSID-password, Trello API link in the credentials.cpp

At some point the root certificate for Trello will expire too. I'll do my best to update the certificate, but if I forget it, it can be changed in this file too.

Using SPIFSS would be great, but current tools don't support Arduino IDE 2.0 yet. The easy way: load the Unicode-supporting TTF font to a microSD!

Of course this was a weekend project to implement first - feel free to send bug reports and improvements, I can't possibly test everything with just one device!
