Zest_Interface_AnalogMux

Overview

The Zest_Interface_AnalogMux is an electronics development board for 6TRON open source IoT platform based on 74HC4067 analog multiplexer from Nexperia.

It permits to direct 16 analog signals to 1 analog input on the 6TRON bus. The multiplexed signal is buffered with an operational amplifier.

The Zest_Interface_AnalogMux offers 6TRON users an analog interface for multiple channels analog measurements.
