This board hosts four 7-Segments LED display. It should be driven by 32 digital PIN from a microcontroller. The kit works best with a series of shift-registers controlled by an Arduino board or another microcontroller. The better way to manage this board with Arduino is using a series of 4 daisy-chained shift-registers, so only three I/O pins are used on the Arduino board.

The kit includes:

• N. 1 50mm x 105mm dual-sided PCB with DIL Socket and 4 8-pins connectors breadboard compatible (green coated + silkscreen)
• N. 4 7-Segments LED Display
• N. 32 SMD limiter resistors
• N. 4 8-outputs connectors breadboard-compatible + the VCC pin

The kit has been tested on many different Arduino boards, from duemilanove up to uno, mini, nano and Arduino-compatible boards.
