I’m cleaning off my workbench. These are parts for which I have no planned projects. Maybe they’re useful to you?
All this stuff is either completely unused, or lightly used by me for testing.
If you want a bunch of stuff, then prices are very much negotiable!

This can be connected to a microcontroller to send stuff over lorawan.
