ESP-12F Serial WiFi Module Mini NodeMCU

The ESP-12F Serial WiFi Module (Mini NodeMCU) is a compact Wi-Fi module built around the ESP-12F, which contains the ESP8266 Wi-Fi chip with a 32-bit processor, flash memory and an on-board PCB antenna. It can run your own program and connect sensors, relays and displays to your network or the internet, so it is a popular low-cost choice for IoT and home automation projects programmed with the Arduino IDE, NodeMCU Lua or MicroPython.

ESP-12F Serial WiFi Module Applications

• IoT sensors that send readings to cloud dashboards or spreadsheets
• Wi-Fi relays, smart plugs and home automation
• Small web servers to control devices from a phone
• MQTT clients for smart home systems
• Learning Wi-Fi, networking and IoT programming

What's in the Box

• 1 × ESP-12F serial WiFi module (Mini NodeMCU)

Tip: The ESP8266 runs at 3.3 V and its pins are not 5 V tolerant, so use a logic level converter when connecting it to 5 V Arduino signals. Wi-Fi transmission causes short current peaks, so power it from a supply that can deliver at least 500 mA.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
