Hi,

Hopefully fpgas count a circuits :)

I am trying to understand how to navigate the documentation for my FPGA

The board is a ice40up5k-b-evn

And I have found the following document for it FPGAUG0200110.pdf
The chip onboard is a iCE40UP5K-SG48
And it appears the pinout document is ICE40UltraUltraPlusSG48PinMigration.xlsx

I have found what I need, which was which pin is the clk, but only because I googled it, found an example, and it worked.

It is pin 35, which is IOT_46b_go. This is mentioned in the pinout document (spreadsheet)
Googling this new found information IOT_46b_go took me to https://www.digikey.jp/htmldatasheets/production/2387226/0/0/1/ice40up5k-mdp-evn.html

And this provided a diagram

Which now confirms it is correct.

It this just life or is there a better way to go about this?

Thanks all and Merry Christmas
