Title: ATXRaspi with ODROID-U3's 1.8V GPIO level?
Post by: siku on March 16, 2014, 11:36:19 AM
Hi,

i am thinking about using the atxraspi with an ODROID-U3 board, which unfortunately has 1.8V on its GPIO lines.

Do you know if the atxraspi works with 1.8V "boot ok" input?

Just in case this does not work: Are you generally open for requests on a modified version of the atxraspi optimized for 1.8v GPIO level for batch orders of about 25-50 units (or maybe even more)?

Thanks for your help!

1.8v is too low, it won't work. But you can use a mosfet to drive the ATXRaspi inputs, just drive the gate with your 1.8v. And perhaps a voltage divider to feedback to your 1.8v system from ATXRaspi.
