ESP-12E ESP8266 Serial Port WIFI Wireless Transceiver Module

ESP-12E ESP8266 Serial Port WIFI Wireless Transceiver Module

The ESP-12E is an ESP8266-based serial port WiFi wireless transceiver module, perfect for Arduino projects and IoT applications. This compact WiFi module can replace the NRF24L01 and allows direct communication with your WiFi router via UART (Rx, Tx) on an MCU.

As one of the most feature-rich modules in the ESP family, the ESP-12E offers the highest pin count and flexibility. It can be programmed to work standalone using the Arduino IDE or with LUA firmware (NodeMCU).

The ESP8266 module is equipped with energy-efficient features like adaptive radio bias and quick switching between sleep and wake modes, making it ideal for low-power applications. It also supports VoIP functionality and includes front-end signal processing for improved performance.

Additionally, the ESP8266-03 is a smaller variant of the module, featuring a built-in ceramic antenna for compact, wireless communication.
