I'm trying to hook up a 16x2 OLED display to a Raspberry Pi, http://www.adafruit.com/products/823
When I connect just the 1st and 2nd pins to the +5v and GND coming off the Pi's GPIO header, the Pi immediately resets, as if it had been shorted or too much current was drawing off it. However, the 50mA +3.3v pin works fine, and I can hook up the rest of the display straight to the GPIO pins and drive it with no problem.
Although the datasheet has the display at up to 30mA, I probably shouldn't be using the +3.3v pin for this(?).
Does the display have any known issues at 5v? Thanks.
