ESP8266 ESP-01S WiFi Serial Transceiver Module with 1MB Flash - 10 Pack

$21.50
SKU 82660001
Now available from PMD Way is the upgrade to the classic ESP01 module - the ESP8266 ESP-01S serial WiFi module. 
 
This is the updated version of the ESP-01E - the PCB layout has changed for an improvement in WiFi radio performance. Otherwise it works the same, including pinout, programming etc. 
 
The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.
 
Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The ESP8266 module is an extremely cost effective board with a huge, and ever growing, community.
 

This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.

Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.

Please note:

This is a 3.3V device, and can require up to ~300mA of current. You cannot reliably run this directly from an Arduino's 3.3V pin. Instead, use a 5V adaptor or external power supply and a level converter to operate with 5V systems.
