Key Features
- Enhanced PCB Antenna: The ESP-12F features an optimized antenna layout compared to the older ESP-12E, delivering better WiFi range, stronger signal stability, and more reliable connectivity in real-world environments.
- Full Metal Shield: Integrated RF shielding minimizes electromagnetic interference (EMI) and improves signal integrity - essential for noise-sensitive and certification-ready designs.
- 4 MB Flash Memory: Generous onboard flash supports OTA (Over-The-Air) updates, complex firmware, web server hosting, file systems (SPIFFS/LittleFS), and dual-partition boot schemes.
- 11 Accessible GPIO Pins: Versatile I/O supporting digital read/write, PWM output, I2C, SPI, UART, and a 10-bit ADC channel - enough for most sensor and actuator applications.
- Ultra-Low Deep Sleep Power: Draws only ~20 uA in deep sleep mode, making it ideal for battery-powered IoT sensors, remote monitors, and energy-harvesting designs.
- Complete WiFi Stack: Supports Station, Access Point, and combined STA+AP modes with WPA2 security, enabling flexible network architectures from simple clients to standalone hotspots.
- Broad Firmware Ecosystem: Program using Arduino IDE (C/C++), MicroPython, NodeMC
