ESP-12F ESP8266 WiFi Module 4MB Flash

The ESP-12F is a powerful WiFi module built around the ESP8266 chip, ideal for hobbyists, engineers, and IoT developers building internet-connected projects, smart home devices, and wireless sensor systems. It supports 802.11 b/g/n WiFi standards, integrates a full TCP/IP protocol stack, and supports both WiFi Direct (P2P) and soft access point modes, making it a flexible standalone solution for wireless connectivity.

This module combines the ESP8266 microcontroller with 4MB of flash memory and a PCB antenna, supporting clock speeds of 80MHz and 160MHz along with RTOS, delivering reliable performance for more advanced firmware and applications. It features an improved antenna design that increases communication distance by 30 to 50 percent compared to the earlier ESP-12E version, along with metal shielding for better RF performance.

With 11 GPIOs available along with UART communication support, this module integrates easily into custom PCB designs and breakout boards. Compatible with Arduino, NodeMCU, and MicroPython firmware, the ESP-12F is a reliable building block for any WiFi-enabled IoT project.
