There are five input pins to the chip which lets you connect one analog pin to any one of 32 analog pins. Of course, in addition to the five control lines, you need some handshaking lines ...

expanding their tests to a number of different analog pins and SAMD21 boards, they saw offsets between 25 mV and 57 mV. It seems like this offset was a known issue; Arduino actually provides code ...

However, Arduino also offers this board without ... Among these, six (A0 to A5) double as analog input pins on both boards. That's where the similarities end. When it comes to the pins' special ...
