SKU: BOB-056 Manufacturer: BC Robotics Inc. Mfg Part Number: BOB-056 Categories: , Tags: , ,


Need to drive high current or high voltage devices with your Arduino, Raspberry Pi, or other 3.3V / 5V logic compatible circuit, microcontroller, or single board computer? This premium 4 channel 10A relay breakout board can handle it! Each relay has the Input, Normally Open, and Normally Closed contact broken out to a nice 5mm pitch screw terminal. The board uses high quality North American sourced parts and logic that is a lot more friendly to common microcontrollers and single board computers. Simply connect 5V power, Ground, and your digital I/O to the 6 pin header and that’s it – no need for any additional components!

As of September 2019 we are now shipping version 1.2 of this board. Version 1.2 adds isolation routing to the board and a few SMD components have been shifted around. It is otherwise functionally identical.

Please Note: While this board is capable of switching higher voltages, please exercise caution. If you are inexperienced or unsure about how to use this product safely we recommend looking at the IoT Power Relay, which has all of its high voltage circuitry fully enclosed.
