BOM list for Digital I/O Board

[crispycritter911]

Does anyone have a BOM for the newer Digital I/O board. 1.2?

This is a partial BOM I'm writing from the schematic iobrd_dig_1.2.pdf (releases folder).

I'm not sure if BZX84-B5V1 and BZX84-C5V1 are both valid for "BZX84 5V1". HE8550G-D-AE3-R is out of stock, and HE8550G-D-AB3-R (available at LCSC) has a different footprint. It would be really nice to have alternatives from sellers like Mouser and Digikey for these components.

I was able to build mine. Thank you for letting me know. I guess I should of clarified a little bit better. What I was trying to find was the package sizes for everything but most of it was 805 with the resistor networks being different. i ended up ordering from 3 different stores. LCSC, Digi-Key and a company in Europe for the SPDIF jack. I've populated the board and have powered it up using the new power switch options. I have yet to test the actual board itself to see if everything is working as advertized. The Digital I/O board will still work with the 3d printed cases. I am using one on thingiverse that is an extended case.

Please, could you specify the part # for the resistor networks?

HE8550G-D-AE3-R is still out of stock at LCSC but I found it here (not tested yet):

Does anybody have an updated BOM or is the one from pacoarcade correct?
