I purchased an Sure 3208 to use with what will eventually be an Arduino Sunrise Alarm clock, but now that I have it in my hands, I'm not sure how to power the board. I've been using this resource to see how to hook it up: http://scuola.arduino.cc/en/content/interfacing-arduino-uno-sure-electronics-led-dot-matrix-based-ht1632c-controller
But I was hoping I wouldn't have to use an external 5v power source.
Can I power this board from one of the arduino pins, or is that too much for the Arduino to handle?
Thanks for your help!
