  • Probably not as it claims "Each one needs 15-20mA Driver Current". You will find lots of similar questions on this site. You are unlikely to get suggestions - this is a Question and Answer site See raspberrypi.stackexchange.com/tour – Milliways Jul 23 '16 at 5:28
  • @JoePlatano not duplicate as the device apparently uses opto-isolators. Still not a great question. – Milliways Jul 23 '16 at 8:12
