Control high-voltage AC/DC devices safely with this versatile 2-Channel DC 5V Relay Module. Designed for seamless integration with a wide range of microcontrollers, this module features built-in optocouplers for reliable isolation and low-level triggering.

Whether you are working on a home automation project, robotics, or an industrial application, this relay expansion board provides a secure interface between your low-voltage control system and high-power peripherals.

Key Features & Benefits:

  • Broad Compatibility: Integrates effortlessly with popular platforms including Arduino UNO R3, Raspberry Pi, 8051, AVR, PIC, DSP, ARM, STM32, and MSP430.
  • Optocoupler Isolation: Ensures safe operation by providing isolation between the control signal and the relay, protecting your microcontroller from surges.
  • Low Level Trigger: Activate the relay with a low voltage (logic low) signal, compatible with most microcontroller GPIO pins.
  • High-Current Capacity: Equipped with high-current relays capable of handling AC250V 10A or DC30V 10A.
  • Status Indicators: Onboard LED indicators provide immediate visual feedback on the relay output status.
  • Efficient Driver: Requires a low driver current of 15-20mA per channel.

Compatibility Details:

  • GPIO 3.3V: Micro:bit, ESP8266, NodeMCU, etc.
  • GPIO 5.5V: Arduino, Raspberry Pi, etc.

This standard interface expansion board simplifies the connection and control of external circuits, making it an ideal component for any embedded systems enthusiast or professional.
