20pcs Smart Electronics CD74HC4067 16-Channel Analog Digital Multiplexer PCB Board Module
A part of the review has been auto-translated.
Well packaged, received in good condition and excellent delivery time (10 calendar days from order). This is a module that is really useful when you need to monitor many analog voltages with a micro-controller that only has a few ADC pins available. You can use up to 4 digital I/O lines to select which of up to 16 analog inputs to poll and then read the selected voltage into a single ADC, I am happy to recommend these modules,
Well packaged and excellent delivery time (7 calendar days from order). These modules let you use 4 digital IO lines to specify which of up to 16 IO lines will be active at any time. Each line can be an analog input or a digital I/O line. They are a good way of extending the number of GPIOs available if the micro-controller has limited available pins and you only need to poll one line at a time. I like to keep a number of these in stock in my hobbyist electronics lab so one is always to hand when I am prototyping circuits. I am happy to recommend these multiplexers.
As describes, not tested but will be OK as past ordered
thank you
