This chip is ideal for connecting more than one analog input/output to the Arduino ESP8266 (which supports only one analog port). For this purpose you connect GND+VCC as usual and... Pin Z to A0 / Y0-Y7 to up to 8 analog devices / S0-S2 to 3 digital ports on the Arduino (binary switching the analog ports 0-7) / E to LOW/GND to enable Switches (see datasheet). The description lacks the supply voltage VCC which is 2V up to 10V and the data sheet which you can find at http://www.farnell.com/datasheets/1645588.pdf
Secondo aspettative, confezionato in busta idonea ai materiali elettronici
Bien, avec ça j'ai de quoi faire, conforme à la description
very good
So far so good
conforme a la description
Not tested yet, but seems of good quality
Well packaged and excellent delivery time (12 calendar days from order). This module lets you extend the number of analog ports on an Arduino or esp by using up to 3 digital outputs to select which of the additional eight analog inputs will be selected and routed to the MCU analog input at any time. I am happy to recommend these items.
I used the circuit to mux the analog input of an ADC. I tested it at 10000 FPS and it works fine.
Last 3 i/o pins a little bit noisy(5-7). Maybe I didn't made perfect soldering.
