OpenSegment Serial Display - 20mm (Red): sparkfun.com/products/11644
OpenSegment Serial Display - 20mm (Blue): sparkfun.com/products/11647
OpenSegment makes it easy to add a large 7-segment display to your project. Because larger 7-segment displays pull more power than a microcontroller is able to drive directly, the OpenSegment has 8 PNP and 4 NPN transistors in order to drive the segments at their maximum brightness!
