Warning to anyone considering this ubiquitous little break out board. It REQUIRES a separate 12-24V power supply just to use the INPUT pins. I don't know what the manufacturer thinks the USB power supply is for, but the terminal block for input p10-p15 is not connected to the 5v power supply as in most other BOB's. This one requires a dedicated external power supply in ADDITION to the USB power supply just to connect an e-stop or limit switch. Also, has a single terminal for the COM for ALL 5 motors. I get economizing, but that can make for a lot of wires trying to connect to a single screw block. Not worth the savings to buy this cheap board.
