ESP-01 WiFi Module ESP8266 - Compatible With Arduino

These modules include 1MB (8Mbit) of flash memory, twice the size of the older blue colored ESP-01 module
The ESP8266 Serial/UART to WiFi module is a great way to connect your Arduino or other microcontroller projects to a WiFi network
Create your next internet of things (IOT) project with affordable network connectivity by implementing this module into your design
The module has the ability to run independent of a host controller
The eight pin header includes two GPIO pins that allow for direct connection of the module to sensors, peripherals, or host controller
