ANAMUX is a 32 Channel Analog Input Multiplexer for Arduino Compatible Boards, at it's heart there are two 74HC4067 Analog Multiplexers. These can be used to read Potentiometers. The first 8 Channels have an selectable 10k pullup resistor each (selectable using solder jumpers) to make it easier to wire buttons as well. You can also use ANAMUX for LEDs!

You can drop ANAMUX inside any MIDI controller including MIDI Foot Controllers, DAW controller and any other arduino project that requires multiple Analog inputs without sacrificing too many inputs from your Arduino, Custom MIDI DJ controller? Yes please!, whats best, The S pins (s0,s1,s2,s3) can be shared across multiple ANAMUX boards, only the SIG pins need to be analog inputs while the S pins only need to be digital!

You will need to wire ANAMUX to your MCU via 8 wires, 4 Digital Pins (any digital pin on your board), 2 Analog Pins (these can be any analog capable pins on your board), VCC (3.3v or 5v depending on your MCU logic level) and GND.

NOTE: the enable pin of the 74HC4067s is not switchable, it is hardwired and always active.

Like all my products, ANAMUX is designed for use in MIDI controllers, however it can be used for any project where an analog multiplexer is needed!

Need a library for Arduino to easily use these? you can use RoxMux or BMC just open arduino, go to Tools > Manage Libraries and search for "RoxMux" and/or "BMC" You can also access them and their documentation here: https://github.com/neroroxxx/RoxMux https://github.com/neroroxxx/BMC
