ESP-12S

The ESP-12S from RF Solutions is an ESP WiFi module. It is a self-contained 802.11 b/g/n WiFi enabled microcontroller featuring the ESP8266 SOC. Pin to pin compatible with other boards in the ESP-12 range but with improved stability and wireless capability. This board has up to 13 usable GPIO pins and an ADC input. It has 4Mbyte flash memory and software updates can be rolled out to it over-the-air. Use it as a cheap and easy way to add WiFi to your Arduino / Raspberry Pi, or use it as a powerful standalone WiFi enabled MCU in its own right.
