ESP8266 ESP12 Wifi Module
Note: We have discontinued this module; we have a drop in replacement with additional features at price. Do check out ESP-12E Wifi Module.
Description:
ESP8266 is not just a UART to Wifi Adapter. It is a SOC comprising of full TCP/IP Stack and host of GPIO pins. You can possibly use it in two ways:
- As a serial to wifi Adapter: In this mode the module can be connected to UART pins of the micrcontroller and can be used as any other wifi sheild. It works with Arduino and all other major micrcontrollers out there. Infact this is the way it was marketed.
- As a MCU and Wifi Sheild with Arduino: However, the community found out the way to access the GPIO pins of the SOC and use it bot as a MCU and a WiFi solution. Interestingly, the community added support for the module to work directly with the Arduino IDE. This way one can program the module itself with arduino style code. To do this, you will require a USB to Serial Convertor like the CP2102.
Note that not all versions of ESP8266 Breakout bring all GPIO pins. This breakout is ESP-12 and it brings out various GPIO Pins. We have used it on one of our projects and works quite well. We were able to interface LEDs, Switches, Ultrasonic Sensor, Relays and Motors. Check the resources links below for more information.
