Quote:The Mux (Multiplexer) Shield adds the capacity for up to 48 inputs or outputs on the Arduino and Arduino Mega.

If you need a lot of inputs and/or outputs, this is your solution! Using three Texas Instruments CD74HC4067 Analog Multiplexers, the Mux Shield makes it possible to have 48 analog/digital inputs or digital outputs in many combinations.

The Mux Shield is available with or without headers for the multiplexer pins, depending on whether you need it for prototyping or for an installation. Both options come with stackable headers. The stackable headers come un-soldered to prevent being bent during shipping.

Features:

* 48 analog inputs/digital inputs/digital outputs (in combination)
* Vcc and Ground header strips (each input/output pin has a dedicated Vcc and Ground)
* Reset button
* PIN 13 LED and Power LED
* Stackable headers (plug directly into Arduino and add more shields on top)
* Arduino Mega compatible
* Requires digital pins 2,3,4,5 and analog pins 0,1,2 – 48 inputs/outputs for the price of 7 pins!
