Made for Hack Club's Undercity
This is a fairly flexible development kit, but for the demo I show it running a very simple WiFi channel scanner, showing the number of stations on each 2.4GHz channel (provided as code.py). Some other things I'm considering for the future are a minimal Slack client, or some sort of over-wifi remote control. Unfortunately a lot of WiFi/USB stuff I wanted to try with it was ruled out, since apparently the esp-32 c3 was not in fact as capable as I though it was. In hindsight, XIAO rp2040 was the way to go.
