IMPORTANT INFORMATION

The standout feature of the JDM-5X is a native 8k polling rate, making 3rd-party Overclocking software unnecessary.
The JDM-5X can be configured via the setup link.
(see Configuration & Tools below)

  • Up to six (6) Remappable Rear Buttons
  • Inner + Outer Deadzone Settings
  • Customizable Stick Curve Response

As this is a custom board, controllers built with this WILL NOT HAVE the following:

  • CONSOLE CONNECTIVITY
  • Bluetooth connection
  • 3.5mm Headphone/Mic Jack
    (For audio, use a USB headset on PC)
  • Rumble / Vibration
  • Touchpad Tracking
  • Battery
DO NOT TRY OVERCLOCKING. It will not work and may make the controller slower.
For the best results, connect your controller with a USB-C to USB-A cable directly to a high-speed USB port on the back of your PC.

MIDAS Modules (HE) are 5-pin Hall Effect thumbstick modules developed specifically for the PS4 JDM-5X board by Marius.

MIDAS stands for Magnetic Integrated Digital Array Sensors—a next-generation technology purpose-built for maximum precision. These modules are uniquely compatible with the JDM-5X and won’t fit standard Sony or Microsoft controllers.

What sets MIDAS Modules apart? They feature a fully circular magnetic sensor for a wider, more consistent signal resulting in reliable control and stability compared to Standard Hall Effect sensors.
The Falcon™ TMR Module sets the gold standard for thumbstick performance in competitive gaming.

Built with advanced Tunneling Magnetoresistance (TMR) sensors, Falcon modules deliver precise, contactless readings for unmatched drift resistance and accuracy.

Engineered for durability and lightning-fast response, these modules raise the bar for controller control and feel.

Trusted by top players who demand flawless execution, every Falcon module is fine-tuned for ultimate competitive reliability.
The Marius DS4 JDM-5X board connects directly to your PC using a USB-C to USB-A cable.

For best performance, plug the cable straight into a high-speed USB port on the back of your PC — avoid using USB hubs or case front-panel ports.

Choosing Nagashock means you get more than just a board—we deliver a professionally assembled, fully tested, and performance-tuned controller built for elite play.

Every JDM-5X installation includes our signature mods, expert calibration, and precision craftsmanship. We rigorously test each controller for speed, accuracy, and reliability to ensure everything works together seamlessly.

From soldering and firmware setup to tension mods and stick calibration, Nagashock handles every technical detail for you—so you can focus on dominating the game with the most advanced PC controller available.

TROUBLESHOOTING & HELPFUL INFORMATION

If your thumbstick directions appear inverted after using the calibration tool, this means the wrong configuration page was used for your specific board version.

Because there are two versions of the JDM-5X board — one for Falcon TMR modules and one for MIDAS Hall Effect modules — each has its own dedicated configuration page.

The pages may look very similar, but they save calibration data differently based on the hardware your controller uses. Using the incorrect page will cause the thumbstick axes to behave incorrectly.

To fix this:

  • Open the correct configuration page for your board version:
    • Falcon TMR Version: Use the “Controller Configuration” link labeled for TMR.
    • MIDAS Hall Effect Version: Use the Hall Effect configuration link.
  • Re-run the thumbstick calibration on the correct page.
  • Save your settings again.

After saving from the proper page, the thumbstick behavior will return to normal.

If your JDM-5X controller isn’t being detected by your PC, follow these steps to complete the initial setup. These steps cover the most common connection issues and will get your controller recognized quickly.

  1. Use a direct, data-capable cable.
    Connect the controller with a reliable USB-C to USB-A data cable (not a charge-only cable).
  2. Connect to the correct USB port.
    For proper 8K polling operation, plug into a USB 2.0 High-Speed port (or better), preferably on the back of your PC directly on the motherboard.
    Avoid front-case ports, hubs, and adapters — these often do not support High-Speed mode.
  3. Open the correct configuration page for your board version.
    • Falcon TMR version → use the Falcon TMR Configuration page.
    • MIDAS Hall Effect version → use the MIDAS Hall Effect Configuration page.

    The pages look similar, but each one saves data differently. Using the wrong page can cause detection issues or inverted calibration.
  4. If the controller is still not recognized:
    Try another rear USB port on your PC motherboard to ensure you are connected to a USB 2.0 High-Speed line.

    We ship every controller fully configured and optimized, including 8K polling enabled by default.
    If your PC doesn’t initially detect it, that usually means your PC’s USB port is not operating in High-Speed mode. Try a different port.
    If it still does not appear, load the latest stable firmware using the Firmware Portal. Firmware reload sets the controller into a safe, lower-polling-rate mode, which makes it easier for any PC to detect. Once the firmware is applied, return to the correct configuration page and click Save once to pair your settings with the new firmware.

    After completing the firmware process, plug the controller into a known-good USB 2.0 High-Speed port on the back of your PC and confirm it is detected. You may then raise the polling rate back to 8K and test again. If calibration is required after loading new firmware, simply follow the prompts on the configuration page to recalibrate and click Save. Once the controller reboots, it will return to normal operation mode. You can use the Polling Rate Verification tool (link above) to confirm the final polling rate.

If your lightbar is flashing green:
This indicates the controller is requesting a firmware update. Open the Firmware Portal, install the latest firmware, then re-save your configuration using the correct page for your board version.

If your controller’s lightbar is flashing green, the board is indicating that new firmware must be installed.

To resolve this:

  1. Open the Firmware Portal (link above) and follow the instructions to install the latest stable firmware.
  2. After the firmware update is complete, open the correct configuration tool for your board version:
    • Falcon TMR Version: use the FALCON TMR configuration page.
    • MIDAS Hall Effect Version: use the MIDAS Hall Effect configuration page.

Once the board is configured after the firmware update, the green flashing will stop and the controller will return to normal operation.
