16x24 LED Matrix power draw?

Post by DaveLister »

What is the max current used by the 16x24 LED matrix (https://www.adafruit.com/product/555)? I'd like to control two of them via a Pro Micro 5V/16MHz and need to know if the 500mA available via the VCC pin is enough, or if I'll have to power them from a separate source.

they're multiplexed so going to guess 100mA draw per display (because only one row is displayed at a time!)
