Esp8266 esp12e serial Wi-Fi wireless transceiver smd module with a DC, spi and extra pinouts esp826612e is an enhanced version esp826612, improve peripheral circuitry increases impedance matching, the signal output is better, whether it is stable or antijamming capability, have been greatly improved, For users before selecting the esp12, it does not matter even if the product has been made, enhanced version is fully compatible with previous firmware, the pin has added six io ports on the basis of the esp12, spi leads. 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 onboard processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its gpios with minimal development upfront and minimal loading during runtime. Its high degree of on chip integration allows for minimal external circuitry and the entire solution, including frontend module, is designed to occupy minimal piece area.
