This project covers the design of a device that displays a to-do list that is pulled live from a Trello board. The whole is based on the Raspberry Pi Zero 2 WH minicomputer and e-paper display.

• Display the current list from Trello
• Automatic synchronization
• Screen refresh only when content is changed

Detailed instructions are available in the form of an article on the mikrokontroler.pl portal
