Hi, I recently bought a PiGlow and have been playing with it, trying to generate various colour-changing effects. It is connected to a Raspberry Pi 1 model B.
I soon noticed that if more than about half the LEDs are on at full brightness, the ethernet port became flakey (the yellow link light flickered and went out); and with all the LEDs on, the RPi crashed. Which is a bit disappointing.
I’m guessing it’s drawing too much current… is that a known problem? Is the bottleneck likely to be somewhere in the RPi itself, or my external PSU (which is rated 5V 1.2A)?
