Based on the Open_Core0 board from the GP2040-CE project located at https://github.com/OpenStickCommunity/Hardware/tree/main/Boards/GP2040-CE%20Official%20Controllers/Open_Core0

Changes from the original design:
- list any changes you make here
The Open_Core0 is my take on a small stickless controller. This was designed from scratch by myself and brings in elements that I believe stickless controller users will enjoy. This is designed to be a premium unit.
A few immediate notes: 1 - Schematics have not been finished yet but will be added at a later time 2 - The RGB turbo LED is currently not implemented in the firmware 3 - The side LEDs are currently not implemented in the firmware
The Open_Core0 is an embedded SMD design with through hole components. It is not recommended to assemble these yourself unless you have a setup to do SMD assembly.
With the Open_Core0 using an embedded RP2040 chip, we are able to access all of the additional GPIO pins that are not easily accessible on the standard Raspberry Pi Pico board. This allows us to have many more options on the board so that people can make truly unique and custom controllers.
We have a small but passionate Discord group which you can access here, if interested: https://discord.com/invite/k2pxhke7q8
A massive thank you to FeralAI who made most of this possible!
The Open_Core0 has a new layout that was modified based on feedback from the community and pro level players. It may not be the perfect layout for you and I encourage everyone to make whatever changes they want. At this time I am not taking requests for changes to the layout.
Six auxiliary buttons are located on the top left side of the board. These represent Start / Select / Home / Capture / L3 / R3.
An 0.96" OLED has been added to allow visibility into current controller settings.
There are two additional aux buttons located to the right of the OLED that are currently unmapped. These are designed to be used with addons in GP2040-CE like turbo, functions, macros (coming soon) etc.
There are two three position slide switches that are mapped by default as a LS/DP/RS slider and as a SOCD mode slider.
There is a single two position slider that is set as a firmware based lockout switch. This was done to allow you to customize what gets locked out when enabled. This can be modified in the web-conifg app further to meet your needs.
The Open_Core0 v2.0 also features a USB passthrough port which will allow you to use an authentication device for play on PS5 games that support legacy controllers (like Street Fighter 6 and Mortal Kombat 11).
You will also find two tactile switches directly on the Open_Core0 board which can be used to reset or boot into Bootsel mode. Near those you will also find debug pins but you will likely not need to use these.
The buttons are designed to take either Choc v1 or v2 switches and there are two LEDs per button.
The Open_Core0 also features RGB LED player indicators. An RGB turbo indicator is on the board but not currently part of the code.
Open_Core0 is the first board to feature RGB LED case lighting! While this code has not been finished yet you will soon have the ability to control case lighting. Please note that when this is finished there will be an update to the case design.
These boards are designed to be made and assembled by JLC PCB. As such, you will find a folder called Hardware files that contains a copy of the three files needed to have these boards made by JLC PCB.
Those files are:
- A gerber file for the design of the board
- A gerber file for the design of the bottom aluminum plate
- A BoM file for the list of parts to be assembled
- A PnP file for the placement of the parts in the BoM file
This design includes both SMD and through hole parts from JLC PCB. There are additional costs associated with having through hole parts added to the board. You can reduce overall costs by removing headers that are not needed for your specific application of the board. This can be done in EasyEDA directly by choosing to exclude the part from the BoM before exporting the necessary files.
These boards have been designed to be fully assembled by JLC PCB less the OLED and hot-swap sockets.
Please note that we are not responsible for issues that arise from the manufacturing of these boards done through JLC PCB or any other manufacturer. These board files have been ordered and tested for functionality.
You will also need the following hardware components to assemble the Open_Core0:
- 0.96" OLED AliExpress Link (make sure you get the module version) Note: You will need to take off the plastic part of the header on it otherwise the plexi will not lay flush! You will also need to snip the legs after soldered on.
- 7x M2x6mm spacer standoffs AliExpress Link
- 8x M2x5mm countersunk bolts AliExpress Link
- 6x M2x8mm buttonhead bolts AliExpress Link
- 12x Choc v1 or Choc v2 switches
- 12x Choc v1 or Choc v2 keycaps
All of the boards so far have been ordered though JLCPCB. Due to minimum order numbers you would get five of these basic breakout boards. Here are the steps to make your first order and what options I choose along the way.
1 - Go to JLCPCB.com
2 - Click on Instant Quote
3 - Click on Add Gerber file and choose the file named Gerber_Open_Core0 v2.0.zip from the Hardware files folder
4 - Choose the following options for the board:
- Base Material = FR-4
- Layers = 2
- Dimensions = (should auto-populate) 250 mm x 131 mm
- PCB Qty = (however large your run will be, minimum of 5)
- Product Type = Industrial/Consumer electronics
- Different Design = 1
- PCB Thickness = 1.6
- PCB Color = (up to you)
- Silkscreen = (defaults to white for all except white boards which is black)
- Surface Finish = HASL(with lead)
- Outer Copper Weight = 1oz
- Via Covering = Tented
- Board Outline Tolerance = +/- 0.2mm (Regular)
- Confirm Production file = Yes (note 2)
- Remove Order Number = Yes (note 3)
- Flying Probe Test = Fully Test
- Gold Fingers = No
- Castellated Holes = No
- No advanced options
Note 1 - If ordering under 50 units you can use single PCB. For orders of more than 50 units JLCPCB will require you to make a larger plate for them. I have compared the costs of doing this for runs in the hundreds and there is only a very small decrease in price over ordering 50 single PCBs at a time. Ordering the 50 single PCBs has the added bonus of coming as individual pieces which do not require additional processing like the plated ones will.
Note 2 - This adds around $1 to the total cost of the order and is 100% worth doing as it will allow you one last chance to catch any issues that may have popped up.
Note 3 - This adds a small cost to the boards but removes the JLCPCB order number. If you are looking to make a run as cheap as possible you can leave this on and either let them place it on the board or add JLCJLCJLCJLC somewhere on the board in silk screen and they will place the order number there.
5 - Choose the following options for the PCB assembly
- PCBA Type = Economic (note 4)
- Assembly Side = Top Side
- PCBA Qty = (however large your run will be, minimum of 2)
- Tooling holes = Added by Customer
- Confirm Parts Placement = Yes (note 5)
Note 4 - Economic assembly is much cheaper on smaller batch runs of 10-30 units. Standard assembly will yield less dead on arrival boards but is more expensive to have done. On average I expect a 5-10% failure rate on the boards from JLC so please factor that in when making your order.
Note 5 - This adds around $1 to the total cost of the order and is 100% worth doing as they will check the placement of all SMD parts and make any necessary changes or reach out if there are concerns. I cannot stress enough that this is the best $1 you will spend for the peace of mind of not messing up an entire batch.
6 - Make sure you have read the terms and conditions of JLCPCB assembly service and then click on the Confirm button if you agree
7 - The Bill of Materials page will show you a render of the board without parts. You can click the NEXT button here unless you see any issues with the board
8 - You will now have the option to upload two files:
- For the
Add BOM Fileyou will need to choose theBOM - Open_Core0 v2.0E.csvfile that is located in the Hardware files folder - For the
Add CPL Fileyou will need to choose theCPL - Open_Core0 v2.0.csvfile that is located in the Hardware files folder
Once these two files have been uploaded you can press theProcess BOM & CPLbutton.
You will likely get an error message here saying that one of the below parts won't be assembled due to missing date. If this pops up and the part in question is NONE1 then you can press Continue because NONE1 is the OLED module and JLC cannot assemble those.
9 - You will now see a list of components that will be used to assemble the boards. If there are no listed issues here you can click on on the NEXT button. (note 6), (note 7)
Note 6 - You can also use this page to omit parts from the assembly. This can primarily be used to not include case side LEDs if you don't plan on offering the LED case in the future. Please only do this if you understand what you are doing as omitting main parts of the design will lead to non-functioning boards. We are not responsible for any boards that are non-functioning.
Note 7 - We have spent extensive time to ensure that the parts chosen will work for this board. If there are any parts that are out of stock, or you get warnings about anything we would recommend you not proceed unless you understand how to find replacement parts. If you are unsure, please feel free to join the Discord and ask us. It is not uncommon for JLCPCB to have part shortages. Most of the parts listed here come back in stock in a few days. If that is the case, you may need to wait to place your order until all needed parts are in stock.
10 - There will now be a render of the board with parts on the Component Placements page. Check this page to make sure that all parts are in the correct spots and orientation. We have ordered based on these files before and they are known to be good. If all looks well press the NEXT button. (note 8)
Note 8 - Please note that we are not responsible for boards made by JLCPCB or any other manufacturer that do note work.
11 - The quote & order page will give you a breakdown of the costs associated with the boards and assembly parts based on the quantity you have chosen. This does not include shipping. Shipping will be calculated at a further step.
- For Product Description I typically choose
OtherOtherand type inController board.
If all looks well here you can click on the SAVE TO CART button.
12 - The Secure Checkout process will be different based on your location in the world. We recommend researching your shipping options to choose the one that is right for your application. If you are planning to also order the aluminum bottom plate then please check out the following section before placing your order.
All of the boards so far have been ordered though JLCPCB. Due to minimum order numbers you would get five of these aluminum plates. Here are the steps to make your first order and what options I choose along the way.
1 - Go to JLCPCB.com
2 - Click on Instant Quote
3 - Click on Add Gerber file and choose the file named Gerber - Open_Core0 v2.0 - Bottom plate.zip from the Hardware files folder
4 - Choose the following options for the board:
- Base Material = Aluminum
- Layers = 1
- Dimensions = (should auto-populate) 256 mm x 134.41 mm
(note 1) - PCB Qty = (however large your run will be, minimum of 5)
- Product Type = Industrial/Consumer electronics
- Different Design = 1
- PCB Thickness = 1.6
- PCB Color = (up to you)
(note 2) - Silkscreen = (defaults to white for all except white boards which is black)
- Surface Finish = HASL(with lead)
- Outer Copper Weight = 1oz
- Via Covering = Tented
- Board Outline Tolerance = +/- 0.2mm (Regular)
- Confirm Production file = Yes (note 3)
- Remove Order Number = Yes (note 4)
- Flying Probe Test = Fully Test
- Gold Fingers = No
- Castellated Holes = No
- No advanced options
Note 1 - The size will come up as larger than the actual board due to how I designed the texture on it. This is OK.
Note 2 - There are only two current color choices for aluminum - white and black. Black currently adds around $20 to the order while there is no additional charge for white.
Note 3 - This adds around $1 to the total cost of the order and is 100% worth doing as it will allow you one last chance to catch any issues that may have popped up.
Note 4 - This adds a small cost to the boards but removes the JLCPCB order number. If you are looking to make a run as cheap as possible you can leave this on and either let them place it on the board or add JLCJLCJLCJLC somewhere on the board in silk screen and they will place the order number there.
If all looks well here you can click on the SAVE TO CART button.

If uploading the firmware before assembly you can hold the BootSel button on the Pico and plug the device into your computer. It will show up as an external device. Copy the GP2040-CE_X.X.X_OpenCore0.uf2 file to it from the main firmware release section (https://github.com/OpenStickCommunity/GP2040-CE/releases) and wait for the device to disconnect after copying completes.
If something goes wrong and you want to upload the firmware again (or if you have tested out the configuration tool and made a mistake) you can enter BootSel mode via either of the methods above and drag over the included flash_nuke.uf2 file. This file will take a moment to write to the Pico, once completed you will see the device disconnect and then re-connect as an external device. After it has shown up again you can copy the same GP2040-CE_X.X.X_OPEN_CORE0.uf2 firmware over to it again.
Through the licensing you are free to make and sell these boards in group buys or even commercial applications.
The intended purpose of this board, as well as the overall GP2040-CE project is to get low cost boards into the hands of as many people as possible so everyone can enjoy the project.
As this is a more premium product that will involve a large amount of manual labor to assemble there are some expected profits for those that are making them.
As such, we have a recommended MSRP of $150 USD for the Open_Core0 or $180 for the Open_Core0 with an included Mayflash MagicBoots v1.1 (for PS5 play on compatible titles). This can be rounded to $165 USD or $195 USD shipped.
You are free to set your own price as you see fit.
Every part of this project is open source, from the GP2040-CE firmware to the original Pico Fighting Board design and also this Open_Core0 design.
Donations are not necessary but always welcome! I typically use donations to pay for Discord boosts and try out new designs or send boards to people for testing, iterations and helping people get board setups that might not be in an economic position to get one themselves.
