ESP-01S ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each of these modules come with pre-programmed AT command set firmware, so you can simply hook this up to your Arduino device and get as many WiFi functionalities as out of the box! It is an extremely cost effective board with a huge, and ever growing, community.

ESP8266 ESP-01S is a ultra-low power wifi transceiver module specially designed for IOT. It support the standard 802.11 b/g/n wireless protocol with STA/AP/STA+AP working mode and serial interface easy to connect to your arduino development board for your DIY wifi projects.
