These arrived from China - I hope they're fine, some of the soldering looks sloppy, but they all have QC stickers :-/ I bought the cheapest ones, I feel bad, exploitation etc., but that's the reality of art projects, it looks like we'll only get around 2/3 of the planned budget, so cutting the board costs by half will be a requirement... https://octodon.social/media/0Qb6fHJHwiy1OeWSLck
@NeuroWinter It's just a board of 16 relays that can be controlled, for example with an Arduino or Raspberry Pi. I'm going to use nine of these to implement a 18-input-channels to 108-output-channels switching system for a sound installation.
