What is the difference between ESP-12E and ESP-12F?

The ESP-12F has an improved PCB antenna design for better WiFi range and signal strength compared to the ESP-12E. Both modules use the same ESP8266 chip and are pin-compatible.

What payment options are available for the ESP8266 ESP-12F module?

You can pay using UPI, credit/debit cards, or Cash on Delivery (COD). All payment methods are available across India.

How do I program the ESP-12F module?

You can program it using the Arduino IDE with the ESP8266 board package installed, or via AT commands over serial from any microcontroller. A USB-to-serial converter is required for standalone programming.

How long does delivery take?

We ship the ESP8266 ESP-12F module across India including Delhi, Mumbai, Bangalore, Hyderabad, Chennai, and Pune. Delivery typically takes 3–7 business days depending on your location.
