The ESP-12S is a compact WiFi module based on the ESP8266 processor from Espressif. Running at 80 MHz with a full WiFi front-end (client and access point modes) and built-in TCP/IP stack with DNS support, it's designed for embedding directly into custom PCB designs.
The module features large, easy-to-solder castellated pads and comes pre-programmed with NodeMCU Lua firmware. Additional components are required for standalone operation.

- SMT Module – Large castellated pads for easy hand soldering
Ideal For
- Custom PCB designs requiring WiFi connectivity
- IoT and home automation projects
- Embedded wireless applications
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Flash memory
- Non-volatile memory that keeps stored data even when power is removed. In this sensor, it matters because enrolled fingerprint templates can remain saved after the project is turned off.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
