ESP8266 ESP-12F 4-Channel Relay Module DC7-28V/5V 30A
This ESP8266-based 4-channel relay module integrates an ESP-12F Wi-Fi module for wireless control of high-power AC/DC loads up to 30A, supporting Arduino IDE development and a wide DC7-28V/5V power input.
Features
- Integrated ESP-12F Wi-Fi module with 4MB Flash for OTA updates and Arduino IDE/MicroPython development.
- Four high-current relay outputs rated for 30A at 5V, suitable for switching loads up to AC 250V or DC 30V.
- Wide-range power supply accepts DC 7-28V or standard 5V inputs, ideal for 12V/24V industrial and 5V USB applications.
- All GPIOs, UART, and program download ports are broken out for secondary development and external sensor integration.
- Onboard reset button, programmable tactile key, and status LEDs for relay operation and Wi-Fi connectivity indication.

This development board merges the popular ESP8266 Wi-Fi SoC with robust relay control, creating a ready-made node for smart home automation and industrial IoT. The onboard ESP-12F module provides full 802.11 b/g/n connectivity and is pre-configured with accessible I/O pins, enabling direct firmware flashing via the exposed serial UART using the Arduino IDE or ESP8266 SDK.
The module’s power design is flexible, accepting a broad 7-28V DC input range commonly found in automotive and security systems, or a standard 5V USB supply for prototyping. Each of the four relays is rated for 30A, allowing direct control of high-power devices like motors, solenoids, and lighting without requiring an external driver circuit. The board includes necessary indicators and user inputs for system status and manual override functionality.
