“Astoundingly good! I have four of these distributed around my property running PainlessMesh controlling my heating system. Relaible comms over wifi and still plenty of IO for temperature sensors, relays leds and switches.”
“In terms of size and low power consumption these are perfect for my battery powered home automation projects, and at a surprisingly low price. The S3 version is even better but they weren't in stock.”
“Fun little micro controller. After initial hiccups installing the appropriate frameworks in the Arduino IDE and finding the settings for enabling serial comms over USB they are a joy to play with!”
