ESP01 ESP-01S (+1Month Warranty) Module WIFI Serial Module 1MB Flash Less Consumption ESP8266 ESP-01S [ElectricA]

New version of ESP01S, with 1MB Flash and Less power Consumption

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

The ESP8266 has 3.6V tolerant I/Os so you will need a logic level converter to connect it with higher voltage devices such as Arduino
The ESP8266 requires 3.3V power so you may need a 3.3V voltage regulator to provide the correct voltage, depending on your setup
