Asked by: James
Hi James,

Thank you for your message, in theory yes provided you ran each one from a different pin and twinned the GNDs.

Best regards

How many motors can you operate off the relay board. I am looking for a cheaper alternative to the motor board.
Kind regards
Asked by: anne
Hi Anne,

Thank you for your question, you could only control one set of motors at a time but you could theoretically connect more motors to do the same action as your first motor. For example if you had a motor that drew about 600mA of power you could connect three in parallel to the board as that would draw 1800mA which is less than the 2A this board can supply.

This is slightly dangerous however as motors often have variable current draw depending on how much voltage you supply them with so I would be quite careful. Also because of the way this circuit works you would consume a lot of power very quickly.

Best Regards
