When I priced out the BeagleBoard Black design, I didn’t know that there was a cheaper BeagleBoard available. It’s the same price at the Feather M0 WiFi, and it’s got several analog inputs, plus I can run Linux on it. The only thing it doesn’t have is WiFi, but there’s a USB port available, and a second one can be attached. So I’d just need a $5 WiFi dongle and a microphone , and I’d be all set.
Where was that noise?
