PIODev Board Populating & odd parts
While most of the parts on the boards are quite off the shelve and easy to procure, there's a few things that need special attention.
The 2x8 and 2x5 debugging headers mentioned in the BoM file are expensive for what they are, and the plastic shell makes it difficult to solder them properly. They can easily be replaced with SMD headers, such as these.
This is the only part that seems to only be sourceable through eBay and others.
It is virtually impossible to source the port as is. There is a page dedicated to talk about replacing it. Other alternatives might include vampirizing the plug from an older cheat cart, such as the MP3Station. Also, the last known active manufacturer for PlayStation carts is cybdyn with their PSIO cart. They might be keen on parting with a few pieces if asked nicely.
When building a PIO Dev Board, while ordering on jlcpcb, the top layer will not be populated. Here are instructions to populate it.
There are 14 bypass capacitors to install. All of them are 603 capacitors, and you can use any generic 25V or 50V 0.1uF capacitor for them. They are all marked with "BP" or "BYPASS".
Overall view of the top layer of the PCB:
The 12Mhz oscillator and its bypass capacitor go here:
There are 12 bypass capacitor right on top of the FT2232H. There also 3 ferrite beads, marked with "FB", and 2 ESD diodes, placed vertically on this picture. Note that the silkscreen is indicating polarity for the ESD diodes, but these components aren't actually polarized. This is to help with installing the diodes, to indicate the left/right positioning. And finally, there is one 4.7uF tentalum polarized capacitor for the FT2232H's built in vcore regulator.
Here is the location for the 5v regulator, with its 10uF input tentalum polarized capacitor, and its 22uF output tentalum polarized capacitor. It has one bypass capacitor on the input side.
And near the PIO plug, there is a SOD-123 schottky diode and a 10uF tentalum polarized capacitor on the 3.3v power line. The diode is polarized the same way as the capacitor.
