Description

First of all my apologies if this is not the right place, it is my first time posting something like this on github.

According to the arduino site the maximum current for the digital I/O pins is 20 mA, but according to the datasheet on Mouser (https://nl.mouser.com/ProductDetail/Arduino/ABX00021?qs=%252BEew9%252B0nqrBypi1Yoqvaaw%3D%3D) and see attached file it is 40mA. Also the uno Wifi 1 is able to handle 40mA.

My question right now is "Which is the right one?".

Research direction

Compare the Arduino site’s stated 20 mA limit with the Mouser datasheet linked in the issue and the attached Arduino_08222018_ABX00021-1391945.pdf for the Uno WiFi Rev2. Confirm which specification applies to the board, then document the authoritative maximum-current value and its source so the discrepancy is resolved.
