This tutorial will help you assemble Picade Max. This is a bit of a mammoth guide, so we'll ‎be splitting it into several parts.‎
Part 4 <- you are here
Plugging in the cables
For this section you'll need:‎
‎2x 50cm USB A to C cables for connecting the Audio and Controller boards‎
‎30cm barrel jack to barrel jack cable for connecting the Power HAT to the display ‎driver board
‎30cm micro-HDMI to HDMI cable for connecting the Pi to the display driver board
Plugging in the USB cables
Plug the USB-C ends of the USB A to C cables into the USB-C connectors on the Picade Max ‎USB Controller and USB Audio boards.‎
Then plug the USB-A ends into your Pi's USB ports.‎
Plugging in the HDMI cable and display power cable
Plug the big end of the HDMI cable into the connector marked HDMI INPUT on the display ‎driver board. While you're here, you can also plug one end of the barrel jack cable into the ‎connector marked 12V IN.‎
Then connect the small end of the HDMI cable to one of the micro-HDMI ports on your Pi ‎‎(we'd suggest using HDMI-0 as it's the default display in Raspberry Pi OS - that's the one ‎nearest the USB-C power input).‎
Plug the other end of the barrel jack cable into 12V OUT on the Picade Max Power HAT.‎
‎1UP or 2UP layout?‎
At this point of the build, you'll need to decide whether you want to use the 1 player or 2 ‎player layout. We'll be showing you the single player assembly steps first.‎
Console assembly (1 player)‎
Fitting the joysticks (1 player)‎
For this part you'll need:‎
Wooden panel M (one player)‎
‎1x joystick‎
‎1x 5 pin joystick cable from the wiring loom‎
‎2x M4 12mm screws‎
‎2x M4 nuts‎
You'll also need the 1 player acrylic console panel and artwork.‎
Flip over the wooden panel so that the label side is facing you. There are some markings to ‎show you where to position the joystick. If you're looking at the panel with the letter M the ‎correct way up, the 5-pin connector should be pointing out of the left hand side of the ‎joysticks.‎
Use the M4 screws and nuts to secure the joystick to the panel. Note that we're only using ‎two of the four mounting holes.‎
Tear off a 5-pin strip from the joystick cable. Use the chunky beige connector to attach the ‎cables to the joysticks.‎
The 5 pin connectors on the joysticks are made of quite soft metal and can sometimes get ‎a little squashed during transit. You might need to bend the pins slightly to straighten them ‎out if you're having trouble plugging in the connector.‎
Position the console panel in front of the cabinet and poke the joystick cable into the ‎cabinet from the front.‎
Feed the joystick cable up over the top of panel K and plug it into the player 1 connector on ‎top of the Picade Max USB Controller board. The connector on the joystick cable has a little ‎moulded arrow to show you where the ground wire is - match this up to the - marking on the ‎board. You can also check that the printed grey markings on the joystick cable is facing ‎towards you.‎
‎(If you find that only the 'up' direction is working on your joystick, you've probably got the ‎connector orientation wrong - try unplugging the connector at the Picade Max USB ‎Controller end, flipping it 180° and plugging it in again).‎
Now that the joystick is attached, flip the console assembly over and place it in its final ‎position on the front of the Picade. We're not fastening it down yet though; you might find it ‎useful to be able to flip it upside down whilst wiring up the buttons.
Next, place your cardboard console artwork on top of the console assembly, art side up and ‎with the holes matching up.‎
Take your acrylic panel and identify the underside. Remove the protective coating from the ‎underside of the acrylic.‎
Then flip the acrylic piece over and place it on top of the console assembly, so that the ‎freshly peeled side is touching the art.‎
It's easiest to remove the protective layer from the top side of the acrylic now, though it is ‎possible to leave it on until later if you want to. If you leave it until after you've fitted the ‎buttons, you'll probably need to remove it in pieces.‎
Add the collar and screw on the joystick ball.‎
Fitting the buttons (1 player)‎
For this section you'll need:‎
The 24 and 30mm arcade buttons
The DuPont pin to spade connectors cables (from the wiring loom)‎
If you're installing the 1 player console, you'll need:‎
‎3x 30mm black button‎
‎4x 30mm blue button‎
‎3x 24mm black button‎
‎1x 24mm blue button‎
‎2x 24mm white button‎
‎14x DuPont pin to spade connectors cables (from the wiring loom)‎
A 24mm button of your choice for the side cabinet button
Separate the cables from the wiring loom into 14 pairs of wires - each pair should have two ‎DuPont pin connectors on one end and two spade connectors on the other. Push the spade ‎connectors onto the terminals on each button.‎
Here's a diagram of the button layout we're using. It has the A, B, X and Y buttons within ‎easy reach, but also maps the L and R 1-3 buttons so you can play both retro and newer ‎games. We're going to be using the button next to 'Start' as our hotkey button and the button ‎on the side of the cabinet for '2P Start', but you could wire up these buttons the other way ‎round if you prefer.
First, we're adding the Start, A, B, X and Y buttons - poke the buttons (and the wires) through ‎the holes in the console:‎
Thread the wires over the top of panel K and plug them into the appropriate connectors on ‎the USB Controller board. We used cable ties as we went along to secure the cables to ‎panel K in groups of 10.‎
Next, we added the Hotkey, Select, and L and R buttons:‎
Next, we'll wire up the side cabinet button.‎
Thread the wires and the button through the hole in panel D, from the outside.‎
Then plug the DuPont pins on the other end of the wire into the 2 player START terminal on ‎the Picade Max USB Controller board.‎
Here's what it looks like with all the buttons plugged in, and with everything tidied up with ‎cable ties.‎
Console assembly (2 player)‎
Fitting the joysticks (2 player)‎
For this part you'll need:‎
Wooden panel L (two player)‎
‎2x joysticks‎
‎2x 5 pin joystick cables from the wiring loom‎
‎4x M4 12mm screws‎
‎4x M4 nuts‎
You'll also need the 2-player acrylic console panel and artwork:
Flip over the wooden panel so that the label side is facing you. There are some markings to ‎show you where to position the joysticks. If you're looking at the panel with the letter L the ‎correct way up, the 5 pin connectors should be pointing out of the left-hand side of the ‎joysticks.‎
Use the M4 screws and nuts to secure the joysticks to the panel. Note that we're only using ‎two of the four mounting holes for each joystick.‎
Split the joystick cable into two separate cables.‎
Use the chunky beige connectors to attach the cables to both joysticks.‎
The 5 pin connectors on the joysticks are made of quite soft metal and can sometimes get ‎a little squashed during transit. You might need to bend the pins slightly to straighten them ‎out if you're having trouble plugging in the connectors.‎
Position the console panel in front of the cabinet and poke the joystick cables into the ‎cabinet from the front.‎
‎
Feed the joystick cables up over the top of panel K and plug them into the connectors on top ‎of the Picade Max USB Controller board. The connectors on the joystick cable have a little ‎moulded arrow to show you where the ground wire is - match this up to the - marking on the ‎board. You can also check that the printed grey markings on the joystick cables are facing ‎towards you.‎
‎(If you find that only the 'up' direction is working on your joystick, you've probably got the ‎connector orientation wrong - try unplugging the connector at the Picade Max USB ‎Controller end, flipping it 180° and plugging it in again).‎
Now that the joysticks are attached, flip the console assembly over and place it in its final ‎position on the front of the Picade. We're not fastening it down yet though; you might find it ‎useful to be able to flip it upside down whilst wiring up the buttons.‎
Next, place your cardboard console artwork on top of the console assembly, art side up and ‎with the holes matching up.
Take your acrylic panel and identify the underside (the underside of the two player one looks ‎like this):‎
Remove the protective coating from the underside of the acrylic.‎
Then flip the acrylic piece over and place it on top of the console assembly, so that the ‎freshly peeled side is touching the art.
It's easiest to remove the protective layer from the top side of the acrylic now, though it is ‎possible to leave it on until later if you want to. If you leave it until after you've fitted the ‎buttons, you'll probably need to remove it in pieces.
Add the collars and screw on the joystick balls.‎
Fitting the buttons (2 player)‎
For this section you'll need:‎
The 24 and 30mm arcade buttons
The DuPont pin to spade connectors cables (from the wiring loom)‎
For the 2-player layout, we're using:‎
‎6x 30mm black button‎
‎4x 30mm blue button‎
‎4x 30mm red button‎
‎4x 24mm black button‎
‎1x 24mm blue button‎
‎1x 24mm red button‎
‎4x 24mm white button‎
‎24x DuPont pin to spade connectors cables (from the wiring loom)‎
Separate the cables from the wiring loom into pairs of wires - each pair should have two ‎DuPont pin connectors on one end and two spade connectors on the other. Push the spade ‎connectors onto the terminals on each button.‎
Here's a diagram of the button layout we're using. It has the A, B, X and Y buttons within ‎easy reach, but also maps the L and R 1-3 buttons so you can play both retro and newer ‎games. With the two-player layout, we're using the button on the side of the cabinet as the ‎hotkey button.‎
First, we're adding player one's Start, A, B, X and Y buttons - poke the buttons (and the ‎wires) through the holes in the console:‎
Thread the wires over the top of panel K and plug them into the appropriate connectors on ‎the USB Controller board. We used cable ties as we went along to secure the cables to ‎panel K in groups of 10.
Next, we added the Select, and L and R buttons:‎
And player 2's buttons:‎
Next, we'll add the side button to the cabinet. For this step you'll need:‎
‎1x 24mm arcade button (small)‎
‎1x DuPont pin to spade connectors cable (from the wiring loom)‎
We've included a couple of extra small buttons, so you can choose what colour you like for ‎the side button.‎
Attach the wires to the button as before.‎
Thread the wires and the button through the hole in panel D, from the outside.‎
Then plug the DuPont pins on the other end of the wire into the HOT terminal on the Picade ‎Max USB Controller board.‎
Here's what it looks like with all the buttons plugged in, and with everything tidied up with ‎cable ties.‎
Adding the backplate
Next, we'll be adding the backplate. There are two versions included (panels I and J) - as ‎we're using a Raspberry Pi, we'll be using panel J which has a round cutout for your Picade's ‎power cable to pass through. It also has a cutout to make it possible to insert/remove the ‎SD card.‎
Panel I is for if you are going down the mini-PC route and want to install a big old PC power ‎supply in the cabinet.‎
Assuming you're using a Raspberry Pi, you'll need:‎
Wooden panel J
‎4x M3 12mm screws‎
‎4x M3 nuts
Insert the tab on panel B into the slot on panel J:
‎
Then attach it in place through the brackets using the M3 12mm screws and nuts.‎
Final cabinet assembly
For this section you'll need:‎
Wooden panel N (the big back piece)‎
‎2x black plastic brackets‎
‎2x long M3 18mm screws‎
‎4x short M3 12mm screws‎
‎6x M3 nuts‎
Remove the console from the cabinet temporarily.‎
Attach the side brackets to the cabinet, using 12mm screws.‎
Fix the console assembly in place using the long M3 18mm screws and the side brackets.‎
Slot the tabs in the back panel into the slots on the base and back. The wooden tabs at the ‎top should hold it in place securely.‎
Time to unpeel any remaining protective coating from the acrylic screen and marquee ‎pieces (savour this moment!)‎
We are done with the assembly! Take a moment to step back and admire your work. Then ‎connect the PSU to the cabinet and see if it works!‎
