I think it might make sense to share the test chips between each other, so that we can rule out problems with the hat or the nucleo board. If anyone wants to send me a chip for helping them test theirs, here is my address: Philipp Gühring Martinstrasse 1/25 1180 Wien AUSTRIA If anyone wants one of my chips, please provide your address, and let me know whether you want a chip on a breakout board, or just a bare chip.

great idea. I'm also happy to send my chips, DM me your address if you want samples
