CrossRoads:
The MAX6953 can control 4 of those 5x7 displays using just 2 IO pins, SCL & SDAMixed-signal and digital signal processing ICs | Analog Devices
Is there anything cheaper? Maybe it could only control one display would be ok. I cant really imagine spending $25 on a chip that ill probably solder wrong and it does not really look like it would go in a breadboard.
