Pinouts

This ESP8266 breakout has a ton of pins available, compared to the mini ESP-01 module. When programming the

breakout in Lua or via the Arduino IDE, you can control these I/O pins to light up LEDs, read buttons, talk to sensors

etc. There's also a bunch of pins for power and control.

The ESP8266 runs on 3.3V power and logic, and unless otherwise specified, GPIO pins are not 5V safe! The

analog pin is also 1.0V max!
