PSPi Zero
The design and testing for PSPi Zero Version 5 is complete. The page on othermod.com got some updates, and now has details on many of the new features. I'll update it a bit more before I start shipping the boards.

I'm estimating $89.95 as the price for the PSPi Zero and Headphone board. This will put it right in line with the PSPi 3 and 4. Manufacturing is a mess right now and prices are all over the place for some components, but I think this price is doable. I might do a fixed $99.95 instead and do free worldwide shipping. The price ends up being basically the same in the end. Still thinking this over. I don't plan to include an LCD with the kit, and I'll link to the eBay page of the company that sells them.

PSPi Compute
The PSPi Compute design work is temporarily on hold because the main 100-pin connector is out of stock and I can't get a prototype ordered.
