ESP-12 (ESP8266 ) is an ultra-low power UART-WiFi module. It has excellent dimensions and ULP technology compared to other similar modules. The module is special design for mobile devices and Internet of Things . Once firmware is upgraded to the appropriate version, a compatible Android device can run the IOT.APK to do the following:control the PWM, I/O pin, or Serial communication. For example,you can use this module transmit date with it serial port.It is easy to communication with other device.
When searching for this over a WiFi network, the device name is "AI-THINKER" and the password is "ai-thinker". In the photos you can see an Android phone running a control app, the APK download is available from here.

Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- 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.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
