USB Relay Board Module 2-Channel

2 Channel USB Powered Relay Module is great for controlling your devices through USB without any USB protocol knowledge. This modules plugs in to your design seamlessly. Individual relays can be controlled by simple commands. The relays are powered from USB bus so it is important to connect this board directly to a PC or to a powered hub.

It has one on board 5V DC relays that can switch up to 10A load.The relays are controlled by USB capable Microchip PIC Microcontroller (PIC18F14K50) and comes with built in firmware that supports simple commands to control relays and read relay status.

Applications

• Home Automation
• Industrial Automation
• Lighting Control
• Garden Equipment Control
• Test Fixtures
• DIY and Hobby

Features

• Good in safety. In power system and high voltage system, the lower current can control the higher one, able to control various appliances and other equipment with high-current current.
