Key Features
- Full WiFi SoC: Complete 802.11 b/g/n stack with TCP/IP - connects directly to any WiFi router without an external microcontroller
- 4MB Flash Memory: The 12F variant includes 4MB onboard flash, providing ample space for OTA updates, web servers, and complex firmware
- 11 GPIO Pins: More I/O than earlier ESP-01 modules - supports UART, SPI, I2C, PWM, and a 10-bit ADC channel
- Metal RF Shield: Improved version over ESP-12E with enhanced shielding for better signal integrity and reduced interference
- Ultra Low Power: Deep sleep mode draws as little as 20uA, ideal for battery-powered IoT sensor nodes
- Arduino IDE Compatible: Program easily using the familiar Arduino framework with thousands of community libraries
- Castellated Edge Pins: SMD-ready half-hole pads for clean PCB integration or breadboard use with adapter boards
- Versatile Firmware Options: Run AT commands, Lua (NodeMCU), MicroPython, or native Espressif SDK - choose your workflow
Why Choose the ESP8266-12F?
- 100% authentic AI-Thinker module sourced from authorized distributors - no clones or remarked chips
- The 12F is the recommended upgrade over ESP-12E with improved antenna impedance matching and RF shielding
- Most popular ESP8266 variant - massive community support, tutorials, and proven reliability
- 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse to most of India
- Expert technical support included - we help you get your project working
- Ideal for both prototyping and production-grade embedded designs
Pin Configuration
