If you need a lot of inputs and/or outputs, this is your solution!
The Mux (Multiplexer) Shield II adds the capacity for up to 48 inputs or outputs on an Arduino. Using three Texas Instruments CD74HC4067 Analog Multiplexers and six SN74HC595 Shift Registers, the Mux Shield II makes it possible to have 48 analog/digital inputs or digital outputs in many combinations, easily handled by the provided Arduino library.
This version improves on the original by moving all of the I/O pins to the end of the board, thus allowing you to add one big connector and hook up a ribbon wire or similar cable solution. This also gets the pins out of the way so that the Mux Shield can be in the middle of a stack, with a shield on top of it, and you can still get to the I/O pins. The pins are arranged into three rows of 16, and each row can be set individually as a digital input, a digital output or an analog input from your Arduino sketch.
Further increasing the flexibility of the board, Mayhew Labs added solder jumpers to the bottom of the board that allow you to shut off this software control feature and "hard wire" the functionality of each row, freeing up the associated Arduino pins for other shields in the stack.
Note: The shield does not come with any headers installed. See the optional recommended products list at the bottom of this page.
Arduino Multiplexer Shield Features
- 48 analog inputs / digital inputs / digital outputs (in total; three configurable 16-pin rows)
- Solder jumpers for selecting hard-wired mode
- Requires only digital pins 2,4,6,7 (and 8,10,11,12 in software-select mode) and analog pins 0,1,2 — provides 48 inputs/outputs for the price of just those 7 pins
