Mux Shield II GPIO expander for Arduino - SparkFun DEV-11723

Shield for Arduino that allows you to increase the number of pins up to 48 pins that can operate as digital inputs/outputs and analog inputs. Board moves the connectors on its side edge, because of this, the connection of the managing board with peripheral devices, you can use one plug.

Pins are placed in three rows - 16 pins in each. Each line can work as outputs, digital inputs or analog inputs. The module uses analog multiplexers 74HC4067 and shifting registers 74HC595produced by the prestigious company - Texas Instrument.

The product is compatible with Arduino
