Updated 3/22/17 – Added Joystick, Corrected LED Indication Wiring

I’ve put a diagram together so you guys have an idea of how to progress. The blue circled connections go to any available green GPIO pin other than 13 and 18, since they are used for audio.

The up/down/left/right from the joystick board go to the same GPIO pins as up/down/left/right from the FPC-10 board

The Process – Most recent update 3/19/17

Before You Begin: This is important and will prevent a future headache

Before you solder anything, you should take a few minutes to verify that your controls work. What I mean by this is plugging your PSP’s FPC-10 cable into the FPC-10 Breakout Board, and make sure that the Up pin connects to the Up pad on the PSP’s small D-pad board (you should get 200 ohms or less for most of the connections), Down on the board connects to Down on the PSPs board, etc. Do the same for all the right-side FPC-24 controls(x, square, on switch, LEDs, etc). It’s better to discover issues now than to find them after everything is soldered up. It only takes a few minutes. I test these before shipping them, but they are hand-made and I’m still only human. This will also help you to know whether your PSP’s buttons and connections are working like they should. The Green LED won’t show a connection because it connects through a mosfet, and the mosfet won’t be enabled without power to the board. All the others should show a connection.

Part 1 – Lithium Module and Power Wires

Install the lithium power module (charge, protection, boost) board on the left side of the case. Some small plastic pieces will need to be removed so it sits into place. This is a good time to solder the LED indication and possibly the power in/out wires to the power module. There will be three indication wires (power on, charging, fully charged) that will lead to the FPC-24 board later on. There will be two wires for power in, two wires for power out, and two wires for battery. These should be the heavier gage wires, since they carry power. Next you can hot glue the power module down, making sure not to get glue on the memory stick slot and cover if you plan to use that later for the microSD card.

Solder the power input wires to the power jack leads, making sure the polarity is correct. The center pin is positive. Route the battery wires to the battery compartment, making sure to leave some extra length.

Part 2 – Audio, SD Card, and FPC-24 Preparation

Solder wires to each of the audio jack’s 4 connections and secure the jack into place. These wires will be used later.

Line up the SD to microSD adapter so that the groove matches up to the position of the microSD slot. This will make the card easier to push in and pull out. Secure the adapter into place while making sure you don’t accidentally glue the door.

Solder small wires to the pins or pads (new version has both pins and pads) on the FPC-24 board. It’s up to you what pads to solder to, but the minimum is the ground, power switch, and the controls.

    • Just re-read your post and I see where it says no audio. I originally thought that meant that there were parts with no audio. So please ignore my initial comment.

      Just from the parts I watched, this is perfect to get a headstart on the build. Looking forward to the edited version and the rest of the build. AWESOME work and highly appreciated!!!!

  1. Any news on the polished edit and finished build? I am curious how you ended up wiring the wireless charger and it’s placement. I was thinking of putting mine on the door for the UMD slot so the system can be centered on the charging pad.

    Still can’t thank you enough for all the time and effort you have put into this project, and I look forward to building another one with the v3 board!

    • Today is actually the first day I’ve had off my 9-5 job in quite a while. Things really picked up at the end of the year. Today I’m trying to get caught up on all the store items that are out of stock and get a few more kits ready. After that I’m testing a couple of the new power boards I designed. Then next on my list is to get the next portion of the build documented. I expect a lot of progress to be made this week. My idea on the wireless charging is exactly the same as yours. I plan to put it on the UMD door.

  2. I know you’re probably super busy, but would it be possible to throw up a quick line sketch showing the wiring connections between all the new boards and the Pi? Mostly looking at the LED connections to the 24-FPC and then to the On/Off board and the Low battery board. Thanks a lot for all your hard work on this.

    Separate note, not sure if you’ve seen this yet but here’s a micro 4-port USB hub as well as a 2-port one. Got the 2 port one and wired in a small USB WiFi device under the D-pad in mine. Just wanted to throw it out there in case you find use for them.

    Thanks again

    • Yea I’ll see what I can do. Doing a bunch of family stuff for the next couple days, but I think I can throw something together soon.

      The USB hubs are very cool. I can tell that they are hand made, and I love that. I’m considering adding one of those chips to a version of the all-in-one down the road.

      • Got everything connected and working except the charging LED when the Pi is off. Can you give a quick description of the Low battery circuit boards connections? I’m using a buck converter to provide the reference voltage. Here is how I currently have it connected:

        Out+ from buck connected to In+ on the Low Battery Board
        Out- from buck connected to GND on the Low Battery Board
        Wire from the battery positive connected to BAT+ on the Low Battery Board
        LED on the Low Battery Board connected to the Orange LED on the FPC-24 board

        Is this all correct? Thanks for the help.


        • I’m putting a diagram together, and I’ll try to post it tomorrow. It should clear up most of the wiring questions.

          You actually don’t need the buck converter to generate the reference voltage. I built it into the low-battery board.

          • Didn’t realize that…awesome, saves me a little bit of space.

            Got it figured out. I removed the buck converter and wired everything up to the low-battery board and was still having the same issue. Then I realized that my 5V supply to the FPC-24 board wasn’t coming directly off the battery . I installed a Teensy 2.0 so I can have true analog joystick control and was powering the FPC-24 board off of that since the connections were right next to each other. So the LED wasn’t getting power when the Teensy was off.

            Re-wired the FPC-24 5V straight to battery in+ on the on/off board and now it works great. Testing out the LED color change now, and then I’ll close it up.

            Thanks again for the hard work on the boards and the projects.

    • I’m working on it. Prototype 2 of the 1000.3 board will take weeks to get manufactured, so I’m trying to get it ordered by tomorrow. As soon as I hit the order button, I’ll switch focus back over to the 1000.2.1. Bear with me guys, I’m spread a little thin.

  3. I realized that you used the center pads on the charging module in your video but not in the photos in the original V2 guide what are the pads used for and do they need to be used?
    I got my kit in not to long ago and am looking forward to the rest of this guide so i can install my low battery and on/off boards.

    • I don’t remember whether I added it to the V2 guide, but I made some changes and used the pads to get charge indication while the Pi was powered off. The orange LED will light when the battery is charging, and it will turn green when it is fully charged. This works when it is powered off or powered on.

      They aren’t required, but it makes the whole build far more useful.

  4. I noticed in this part one guide that you didn’t wire up the internal speakers but in the V2 guide you did. Are they going to be used in a part two guide? I think I may have misplaced mine

  5. yes, i’m waiting on the video.
    also, i seem to have misplaced the wifi switch from my kit. only place i can find to order another one (separate from the board, switch only) is in China. roughly a 3-4 week delivery. i would gladly pay for the switch/shipping from you if you have any for sale.

  6. I’m waiting for the video as well. Also what are you using the wifi switch for in the build is it for wifi or something else cause mine is broken and don’t know if I need it for the build or not. Thanks.

    • You can now

      Everyone out there, if you previously purchased a kit then add a note when you order this. I’ll refund part of the price.

      I’ve been using the ones from the PSP’s dead motherboards, but I’ve had lots of people contact me saying they are hard to remove. That’s why I threw them in with the new kits.

      I’ve also got a bunch of PSP audio jacks on the way. I’m not going to include those with the kits because they are a little pricey, but I’m making them available too for people that aren’t able to remove their own.

    • Getting the first group of 20 Version 3 boards out over the next couple days, then I’ll be waiting for the next batch to arrive. I’ll work on the videos while I’m waiting. The goal is to knock out a couple parts of the video at once.

        • The only wires that have to go to specific places are the GND, 5V, green LED, orange, LED, and power switch. Everything else can go to any GPIO pin. You’ve just got to tell the software which pin to use.

        • { 26, KEY_UP }, // Up
          { 20, KEY_DOWN }, // Down
          { 21, KEY_LEFT }, // Left
          { 19, KEY_RIGHT }, // Right
          { 17, KEY_Q }, // Square
          { 24, KEY_ENTER }, // X
          { 25, KEY_Y }, // Triangle
          { 23, KEY_ESC }, // Circle
          { 6, KEY_LEFTCTRL }, // Left Trigger
          { 5, KEY_RIGHTCTRL}, // Right Trigger
          { 22, KEY_S }, // Start
          { 27, KEY_D }, // Select

          This might help you. It’s the code I used in Adafruit’s Retrogame. That’s the GPIO pins I used for each function and the key I assigned to each function.

          • Can u please update the wording diagram for the 2.1 build it not the same as u show in the video.for 1 it don’t show the middle led out of the charge board,i get Orange carging when it’s on and green when it’s full but no charge indication in the off possition

          • I cleared up the LED wires.

            I made a mistake in the image for where the +5v from the FPC board attaches. Thanks for pointing it out. It has to hook directly to the 5v coming from the lithium module (you can hook it to the +5v in on the on/off board) or you won’t get charging LED’s when it is off. It’s fixed.
