The AZDelivery ESP8266 ESP-01S WLAN WiFi module is designed with high quality materials, it is small, convenient and powerful, making it suitable for small or large projects. The best feature of ESP8266 is that it gives you WLAN communication, so you can use it to connect to your WLAN network or connect to the Internet. Host a web server with real web pages, have your smartphone connect to it, etc.

Special features
- This module is an independent SOC (System on a Chip) that does not necessarily need a microcontroller to manipulate inputs and outputs, because the ESP-01S acts as a small computer.
- Whether used as a WiFi adapter in conjunction with an Arduino, or in stand-alone mode, due to implemented TCP/IP stack your project with this microcontroller will be WLAN-enabled.
- Programming is available via the Arduino-IDE, as well as with LUA or Micro Python.
