Badger2040 accessories

The Badger 2040 has been around for a couple of months, and Les Pounder from Tom’s Hardware reviewed the board in March. He was rather satisfied with the experience notably with the easy-to-use library, the nice-looking screen, the Stemma QT connector for expansion, and support for both USB and battery power, but lamented the lack of an on-board charging circuit, and Pimoroni does not provide an enclosure. The good news is that Andreas Känner released a 3D printable case in April a few weeks after the review.
