Weirdly coincidental timing on this! I've been working on a PCB design (FeatherWing form factor) to track weather data on my hikes, making use of a BME280 and a GPS module. First revision of the board[1], I discovered that the sensors started out accurate, then drifted up to a steady 3° above ambient. Probably because the GPS module was heating up. So last night I found myself reading up on design considerations for temperature sensors [2], including specific things like the cutout you have on the left side of this board.
I'm guessing you designed this — any advice as I embark on designing a second revision of my hiking log?
Note that to get it to support Spotify Free, you need to compile a custom librespot with this part of the code commented out, that checks for Spotify Premium: https://github.com/librespot-org/librespot/blob/6dc7a11b09b5...
And then use this with spotifyd instead of the original.
