Hi all!

Our lovely sudoor access system is currently broken. Things look okay from the server side, so it's likely a hardware issue. Granted, the whole thing is a bit janky, so I think it's finally time to upgrade to sudoor v2. I'd like to fix it, but don't have experience, so I thought I'd come to Microcontroller Hacking Night tomorrow and see what I can do. If anyone owns or could suggest where to procure the following, that'd be rad!:
