ESP-12F ESP8266 Wifi Wireless Module

ESP-12F ESP8266 Wifi Wireless Module

The ESP-12F Wi-Fi Module is a highly integrated Wi-Fi and microcontroller solution based on the ESP8266EX SoC, offering excellent performance, reliability, and compactness for IoT and wireless networking applications.

It is an upgraded version of the ESP-12E, featuring an improved PCB antenna design, enhanced signal stability, and better RF performance. The ESP-12F integrates the full TCP/IP stack, 32-bit Tensilica LX106 processor, and 4MB flash memory, making it ideal for standalone IoT systems or as a Wi-Fi adapter for microcontrollers like Arduino, STM32, and Raspberry Pi.

With support for multiple communication interfaces (UART, SPI, I²C, I²S, ADC, PWM) and 11 GPIO pins, the ESP-12F provides excellent flexibility for various embedded and automation projects.
