Esp8266 Module 12v Esp-01 – Description:
This WiFi relay module carries an ESP8266 WiFi module and microcontroller. It sends serial port instructions to the cell phone APP and implements wireless control of the relay within the local area network (LAN).
This module is ideally suited for controlling larger voltages in your project through WiFi. It is a 2-channel relay module that can be used to activate up to 250V AC and 30V DC. This allows you to build device control systems, operate remote lights, or trigger systems when the module is supplied with a signal from an ESP8266 module.
The module has an LED that lights up relative to its state. A red power activation LED lights when a signal is received on the IN pin. When a signal is received, an audible click can be heard as the relay triggers, connecting the output pins. The relay is controlled via the included ESP8266, which requires configuration via UART before full operation. Once programmed and powered, it runs independently, making it ideal for use in Internet of Things (IoT) projects.
How to Use:
-
5V/1A power adapter and APP “ESP Touch–Demo”
-
Connect the 12V/1A power adapter, with the positive and negative poles of the power connected to IN and IN- of the module, respectively.
-
Install the ESP Touch–Demo app on your Android device to configure the WiFi account and password for the ESP-01 module in Work Mode 2.
-
Install the Easy TCP–20 app on your Android device. This TCP transmission tool is used to send relay control instructions. Click on SWITCH, then enter the two relay control instructions and names (in HEX format) in the gray blocks of the interface.
Features:
-
Transmission distance:
-
In an open environment, the maximum stable transmission distance is 100M when the mobile phone is mounted on the WiFi module.
-
When the WiFi module and mobile phone are connected to the router, the transmission distance depends on the router’s signal strength.
-
-
Uses Smart Config technology in the mobile app for ESP-01 WiFi module configuration, with username and password memory function.
-
Onboard 12V, 10A//250V AC 10A//30V DC relay, capable of 100,000 continuous pulls, with diode discharge protection and short response time.
-
Board mode selection and real-time working status indicator.
-
Reserved UART debug interface and STM8 SWIM program download interface.
Package Includes:
-
1 x ESP8266 ESP-01 12V 2 Channels WiFi Relay Module Things Smart Home Remote Control Switch

Frequently Asked Questions
Can I flash custom firmware on the ESP-01 while it’s on this relay module?
Yes. The module exposes the ESP-01’s programming pins, allowing you to enter flash mode with a USB-to-TTL adapter. After flashing, restore the connections for relay control.
What power supply specifications are required for reliable operation?
Use a regulated 12 V DC supply capable of delivering at least 500 mA. Ensure proper grounding and minimal voltage drop to avoid ESP8266 brownouts during WiFi transmission.
How do I wire a 230 VAC light to the relay safely?
Connect the live wire of your 230 VAC circuit to the COM terminal and the switched live to the NO terminal on the chosen channel. Always isolate power before wiring and follow local electrical codes.
