Unfortunately, even a 64 x 64 grid uses a surprisingly large amount of power and you'll find yourself working with high current DC power supplies.

- iamflimflam1 6y agoYes, you need to start injecting power along the strings of LEDs to keep it working properly and the power demands do add up pretty quickly. Fortunately it's low voltage (5v) so not shock worthy, but definitely capable of starting fires!
