WiFi Module – ESP8266 (ESP-12E SMD)


SKU: WL-008 Categories: ,


This is the ESP8266 WiFi Module chip in “ESP-12E SMD” footprint. This type allows you to access all the I/O pins available in the ESP8266 wifi chip and use its full features. Adding WiFi connectivity now become more easy!

Pair this chip with an adapter board ESP12-E SMD to male header adapter to easily access the pins. Don’t forget to get a Voltage Regulator – 3.3V, USB to UART Serial TTL adapter cable PL2303, Logic Level converter 5V and 3.3V, Capacitor Electrolytic – 1000uF to complete your parts and program the ESP12-E chip. Maybe you can also get a Power Supply Adapter 12V/600mA to power your circuit.

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow 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, and the entire solution, including front-end module, is designed to occupy minimal PCB area.
