The Blackmagic Design Spares - Camera URSA Mini Pro G2 - PCB USB-C is the dedicated interface board that houses the high-speed USB-C expansion port found on the side of the URSA Mini Pro G2. This board is a critical component for modern workflows, as it enables direct recording to external SSDs and the use of the Blackmagic URSA Focus and Zoom Demands.
High-Bandwidth Data Path
Unlike standard USB ports on a computer, this PCB is engineered to handle the massive data sustained rates of Blackmagic RAW at high frame rates.
-
USB 3.1 Gen 1/2 Support: Provides the 5Gb/s or 10Gb/s (depending on the internal controller's negotiation) required for recording 4.6K G2 footage directly to external media.
-
Power Delivery: Manages the 5V power output required to spin up external bus-powered SSDs.
-
Expansion Logic: Acts as the communication bridge for the URSA’s side-car accessories, translating USB commands into the camera's internal bus language.
Why You Might Need a Replacement
The USB-C port is one of the most vulnerable physical points on the URSA Mini Pro G2 because it is frequently used with external cables that can be yanked or snagged.
-
Physical Port Damage: The internal "tongue" of the USB-C port is fragile. If a cable is inserted forcefully or bumped sideways, the pins can bend or snap, leading to "Disk Not Found" errors.
-
Intermittent Connection: If the camera frequently stops recording or "drops" the external drive when the cable is wiggled, the solder joints connecting the port to the PCB have likely developed micro-fractures.
-
Electrical Surge: Using poor-quality USB-C cables or faulty SSD enclosures can cause an electrical short that "blows" the surface-mount fuses on this specific PCB.
-
Port Wear: After hundreds of plug/unplug cycles, the mechanical "click" of the USB-C port can wear out, causing cables to fall out during operation.
Key Features
-
Genuine OEM Part: Designed to fit the specific internal mounting standoffs of the G2 chassis.
-
Isolated Design: Being a separate PCB means you don't have to replace the expensive Main Board just because a physical connector is broken.
-
Shielded Construction: Engineered to prevent electromagnetic interference (EMI) from affecting the camera's sensitive audio or video circuitry.
Technical Installation Note
Replacing the USB-C PCB requires opening the side panel of the URSA Mini Pro G2. This is a delicate procedure:
-
Ribbon Cable Caution: The PCB connects to the Main Board via a fine-pitch ribbon cable. Ensure the locking tab on the connector is fully raised before removing the cable to avoid tearing the contacts.
-
Gasket Alignment: Ensure the rubber weather-sealing gasket around the USB-C port is perfectly seated before closing the chassis. If it's pinched, moisture can enter the camera body.
-
Cable Strain Relief: Once the new board is installed, it is highly recommended to use a "cable protector" or "clamp" (like those from SmallRig or Tilta) to prevent future physical stress on the new port.
-
Testing: After installation, test the port with both a high-speed SSD and an URSA Demand (if available) to ensure both data and power delivery are functioning correctly.
Expert Tip: Before ordering this spare, try a different, high-quality USB-C cable (rated for 10Gb/s or higher). Many "failures" are actually just worn-out cables rather than a faulty internal PCB!
