In this document: https://wizwiki.net/wiki/lib/exe/fetch.php?media=products:wiz610io:wiz610io_user_manual_v1.0.pdf on page 4 there is a pinout diagram of the WIZ610io module. It is incorrect. The pinouts in the Reference Schematic on page 14 look to be correct.
At the top of the page are 2 connector drawings. They are incorrect.
A little further down the page is a module graphic. It is incorrect as well. It does not match the connector drawing above it, and even if it did, that drawing is wrong.
J2 pin 1 is GND
J1 pin 3 is MOSI
J2 pin 6 is MISO
