Monk Makes Dual Relay Module for 3.3V/5V Microcontrollers

The Monk Makes Dual Relay Module is a straightforward, two-channel relay board designed for reliably switching low-voltage AC and DC loads. It is the ideal solution for hobbyists, educators, and electronics enthusiasts looking to interface their microcontroller projects with higher-power components.

This module is specifically engineered for compatibility with popular 3.3V and 5V microcontroller platforms, including Arduino, Raspberry Pi Pico, and ESP32 boards. It simplifies the process of controlling devices like light bulbs, small motors, and heating elements directly from your digital pins.

Key Features & Specifications

• Dual Solid-State Relays: Features two independent, opto-isolated AC/DC solid-state relays, providing electrical separation between your sensitive control circuitry and the load for enhanced safety and reliability.
• Switching Capacity: Capable of handling a maximum switching voltage of 16V, with a peak current of 2A (for durations under one minute) and a continuous current rating of up to 1.5A.
• Built-in Protection: Each channel is safeguarded by a resettable polyfuse, offering protection against over-current conditions and improving the module's durability.
• Clear Visual Feedback: An integrated active LED indicator for each relay provides immediate visual confirmation of the switching state, aiding in project debugging and operation.
• Flexible Connection Options: The module is supplied with screw terminals for easy, secure wiring of your load, and header pins for connection to your microcontroller (soldering is required for the headers).
• Compact Design: With board dimensions of 64mm x 35mm, it is a space-efficient addition to any project.

Important Safety Note: This product is designed exclusively for switching low voltage DC loads only. It must never be connected to AC (mains) voltage under anycircumst
