I have no idea what it is but I got one for free. Not to sound like I’m advertising for Arduino. Signed up for monthly plan for their create studio. Paid $2.70 for shipping. I guess I’ll play around with WiFi. Not that into WiFi but it’s was free. Thanks Arduino guys!
Nice it’s got a SAMD M0 with 256k wow that’s a lot of memory. It’s probably more than I will ever need. I can do quite a bit with an ATTINY.
