5. Setup Guide

Follow these steps to set up your RGB Matrix Power Adapter:

1. Connect Power Input: Choose one of the two available power input ports. You can use a Type-C USB cable (e.g., from a phone charger or power bank) or a DC-044 barrel jack power supply. Ensure your power supply meets the voltage (5V) and current requirements (up to 4A for Type-C, up to 8A for DC-044) for your RGB matrix panel.
2. Connect RGB Matrix Panel: Use the provided VH3.96 cables to connect the power input of your RGB LED matrix panel(s) to the "PWR OUT" ports on the adapter. The adapter has two such ports, allowing you to power up to two panels if the total current draw does not exceed the adapter's capacity.
3. Connect MCU (Optional): If you are powering a microcontroller (e.g., ESP32, Raspberry Pi) from this adapter, use the provided HP2.0-4P cable. Connect one end to the PH2.0-4P port on the adapter and the other end to the appropriate 5V and 3.3V power input pins on your MCU. This eliminates the need for a separate power supply for your MCU.

6. Operation

Once all connections are securely made as described in the Setup Guide, the RGB Matrix Power Adapter will automatically begin supplying power to the connected RGB matrix panels and MCU. The onboard over-current and TVS protection mechanisms will actively monitor the power flow, providing safeguards against potential electrical surges or excessive current draw, ensuring stable and reliable operation of your system.

7. Maintenance and Care

To ensure the longevity and optimal performance of your RGB Matrix Power Adapter, please observe the following guidelines:

• Keep Dry: Avoid exposing the adapter to moisture or liquids. Damp environments can cause short circuits and damage the electronic components.
• Handle with Care: The adapter contains sensitive electronic components. Avoid dropping it or subjecting it to strong impacts.
• Static Electricity: Be cautious of static electricity, especially when handling the adapter or connecting components. Discharge any static buildup before touching the device.
• Cleaning: Use a dry, soft cloth to clean the adapter. Do not use harsh chemicals or abrasive cleaners.
• Ventilation: Ensure adequate airflow around the adapter, especially during prolonged operation, to prevent overheating.

8. Troubleshooting

If you encounter issues with your RGB Matrix Power Adapter, consider the following common troubleshooting steps:

• No Power Output:
  • Verify that the power input source (Type-C or DC-044) is properly connected and providing the correct 5V.
  • Ensure the power supply itself is functional and capable of delivering sufficient current for your connected devices.
  • Check all cable connections to the RGB matrix panel and MCU for secure fit.
• Intermittent Power:
  • This could indicate an unstable power input. Try a different power adapter or cable.
  • Ensure the total current draw of your connected devices does not exceed the adapter's maximum output capacity.
• Device Not Functioning:
  • Confirm that the RGB matrix panel or MCU is correctly wired to the adapter's output ports (5V, GND, 3.3V).
  • Rule out issues with the connected device itself by testing it with an alternative power source if possible.
