Preorder Status: There are currently 62 preorders. I’ll give an estimated wait time once I get the first orders shipped.
The final prototype arrived a little early. I did a test build, and so far everything looks good. I’ll post an update once I stress test everything.
This means the design work is finished on V3.
Thanks for voting guys. This definitely rules out Green, and Red didn’t get too many votes either. It’s between Black and Blue. I’ll make the final call after the new board arrives.

The Prototype 2 test build is complete. I made some pretty substantial changes to the board, some to make the board function better and some to make the assembly process easier. Enough changes were made that I believe a Prototype 3 is needed.
The expectation is that this board will be the final design, and that there won’t be any more changes needed. I’m going to put a small order in (20 or so) at first. Once I’m satisfied with the quality I’ll place a larger order.
Prototype 2 arrived and I’m putting it through some tests. The Pi gets soldered directly to the board. All GPIO connections and SD card connections get routed through the board. The board has a switch in the position of the PSP’s original Wifi switch, and it is used to turn the audio on and off. The PSP’s power input connector is included, so no soldering is needed for it. The battery gets soldered to the bottom opposite the power connector. USB is included. I’m really happy with the results, and so far it looks like only a couple small tweaks need to be made to the final version. Check it out below.
PSPi 1000 Version 3 is going to be a little different, and will start with me designing a custom PCB. Instead of manual soldering of the wires, a PCB will interface with the FPC connectors and GPIO. Initially the plan was only to make a board that interfaced with the FPC, but this grew into an all-in-one. It doesn’t integrate every feature, but it integrates most of them. The end result will be a project that takes hours to complete instead of days or weeks. Hopefully this will open the project up to more people that want to build it. This won’t be a drop-in replacement for the original PSP board, and it will still require some decent soldering skills, but the process will be simplified.
The hardest part of this design has been the PSP casing. Fitting everything in properly, getting the mounting holes lined up, lining up the USB, and orientation of the Pi has been very difficult. I didn’t have anyone else’s work as a starting point, so this has been a slow process. I’m almost there though.
These circuits will be included on the PCB:
LED Status Circuit for Charging and Low Battery
Raspberry Pi Low Battery Warning LED Circuit
Raspberry Pi Zero Audio Filter Circuit
Updated On/Off Circuit
Simple Joystick using LM339
Audio Amplifier Using PAM8403
Lithium battery management (proper lithium charging, protection, and boosting to 5v)
Overall PCB design progress – Updated 1/4/17 – Features Locked, No Additional Features Will Be Added
