ESP8266 ESP-12S WiFi module - ESP12-S

ESP8266 ESP-12S WiFi module

The ESP12S module is based on the ESP8266 chip. Operates on Wifi 802.11 b/g/n at 2.4 GHz. This is the newer brother of the "E" version, in which the antenna was improved, thanks to this treatment increased network coverage by up to 30%. The module has passed FCC, CE and ROHS certification, in addition, digital input / output filtering has been improved. Cloud services have also been implemented so you can use 3 simple commands.

This device can be used as a converter to connect a microcontroller to Wi-Fi or as a standalone device, as it has a controller with FLASH and ROM memory.

ESP12 has 4MB of Flash memory. It is possible to program the module using LUA scripts, Arduino IDE or AT commands.

So that the module can be handled conveniently we recommend adapter for ESP8266 chips

In this post on our BLOG you will learn how to add ESP8266-based modules to the Arduino environment so that you can write code for them in the simple Arduino IDE environment.
