4 digits display [module]
Version 1 - Last update: Oct 26, 2015

4 digits, 7 segments display module with integrated multiplexers and resitors; the module is desgiend around the YSD-439AB4B-35 display (https://www.sparkfun.com/products/9481); I designed this module because it is a real pain to use this thing on a breadboard! This module is part of a display board driver which uses an ATtiny2313 to control the multiplexers, and which will get commands via the UART port (TX and RX), so that you will use just 4 pins to control it! :D
