Mini USB Interface Board

Monitor and control your devices with the Velleman VM167 Mini USB Interface Board. The VM167 is similar to the Arduino in that it contains GPIO, but it’s more than just a relay card. The VM167 has two PWM (pulse width modulation) outputs, a single pulse counter, and has the ability to read and send digital signals allowing this module to control relays, sensors and even stepping motors.

Do you need more inputs and outputs than are offered with a single VM167? No worries, connect up to two mini USB interface boards via your PC’s USB connectors to expand the amount of inputs and outputs available. All communication routines are contained in the included DLL (Dynamic Link Library) which supports Windows XP, Windows Vista, and Windows 7.
