ESP-07 ESP8266 Serial Wifi Module

Was able to get this hooked up to an Arduino within minutes, and the signal range is noticeably better than the previous modules I've tried. Perfect for adding wifi to my home sensor projects without taking up too much space on the breadboard.

Swapped my old ESP-01 for this, and the extra GPIO pins on the ESP-07 make wiring up sensors so much easier. Connecting to my 2.4GHz network was straightforward, and it's been rock solid for pulling weather data.

Had my ESP-01 gathering dust because I needed more GPIO pins, and this board finally gave me the breakout I was after. The onboard PCB antenna works fine for my kitchen sensor, and hooking it up to an Arduino took about ten minutes with the usual AT commands.
