SunFounder 2-Channel DC 5V Relay Module with Optocoupler Low-Level Trigger Expansion Board

The 5V 2-Channel Relay interface board is a versatile device that offers a standard interface, allowing for direct control by a microcontroller. Each channel on the board requires a driver current of 15-20mA. The board is equipped with high-current relays, capable of switching AC 250V at 10A or DC 30V at 10A.

The board's compact size, measuring 50.5mm (L) x 38.5mm (W) x 18.5mm (H) (1.99 inch x 1.54 inch x 0.73 inch), makes it a convenient choice for a wide range of applications. It is compatible with various microcontroller platforms, including Arduino, Raspberry Pi, 8051, AVR, PIC, DSP, ARM, MSP430, and TTL logic.

One of the key features of this relay interface board is the inclusion of indication LEDs that provide visual feedback on the status of the relay outputs. This allows users to easily monitor the activation and deactivation of the relays, enhancing the overall user experience.

Overall, the 5V 2-Channel Relay interface board offers a robust and versatile solution for those seeking to integrate high-current switching capabilities into their projects. Its standard interface and compatibility with a wide range of microcontrollers make it a popular choice among hobbyists, engineers, and system integrators.
