As the attached photos seem to show, MicroConnect Safe Charge USB-A data blocker adapter data pins seem present, while they should not. Is there a scheme or photos showing if the data pins are connected from an end to the other one?

The MicroConnect Safe Charge USB-A data blocker is designed to physically block the data pins (D+ and D-) in a USB-A connector, allowing only the power pins (VCC and GND) to pass through. This ensures that only charging occurs, and no data transfer can take place.

Key Observations from Your Images:

  1. Top View (First Image):

    • The USB-A connector shows metallic pins, but it is unclear whether the data pins (D+ and D-) are internally connected or isolated.
    • The "P" marking (likely indicating "Power Only") suggests it is intended to block data.

  2. Bottom View (Second Image):

    • The internal structure shows a white plastic barrier, which is typical in data blockers to physically separate the data pins from the power pins.
    • The metallic contacts for the power pins (VCC and GND) are visible, but the data pins should be isolated or absent.

How Data Blockers Work:

  • Physical Isolation: A proper USB data blocker will have the D+ and D- pins removed, covered, or not connected to the corresponding pins on the other end.
  • Schematic Confirmation: If you want to verify, you can:
    1. Use a multimeter to check continuity between the data pins on both ends. If the data pins are truly blocked, there should be no continuity between the D+ and D- pins from one end to the other.
    2. Disassemble the adapter (if possible) to visually confirm that the data pins are not connected internally.

Expected Behavior:

  • Power Pins (VCC and GND): Should be connected from one end to the other.
  • Data Pins (D+ and D-): Should not be connected or should be physically absent/blocked.

What You Can Do:

  1. Test with a Multimeter:

    • Check for continuity between the data pins (D+ and D-) on both ends. If there is continuity, the adapter is not blocking data.
    • If there is no continuity, the adapter is functioning as intended.

  2. Visual Inspection:

    • If you can safely open the adapter, look for physical barriers or missing connections for the data pins.

  3. Check Manufacturer Documentation:

    • Look for official schematics or teardowns of the MicroConnect Safe Charge model to confirm its design.

Would you like guidance on how to use a multimeter for this test, or do you need help finding official documentation?
