Banggood

Secondo aspettative, confezionato in busta idonea ai materiali elettronici

Bien, avec ça j'ai de quoi faire, conforme à la description

So far so good

conforme a la description

Not tested yet, but seems of good quality

Cadeau utile, rien à redire

I have no idea how to use this but it arrived quicker than expected.

Perfect

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/datashee

But they were a lot bigger and more complicated, this is so cool an 8 channel multiplexer just a little bigger than my fingernail, can't wait to try it.
