The following table outlines the key technical details of the UGREEN Revodok Pro 109 9 in 1 USB-C Hub:

The UGREEN Revodok Pro 109 does not have traditional pins but features the following ports:

1. Connect the Hub to Your Device:

   • Plug the USB-C connector of the hub into the USB-C port of your laptop, tablet, or smartphone.
   • Ensure the host device supports USB-C with DisplayPort Alt Mode for HDMI functionality.

2. Connect Peripherals:

   • Use the HDMI port to connect an external monitor or projector.
   • Plug in USB-A devices such as keyboards, mice, or external drives.
   • Insert SD or microSD cards into the respective slots for data transfer.
   • Use the Ethernet port for a wired internet connection.
   • Connect headphones or microphones to the 3.5mm audio jack.

3. Power Delivery (Optional):

   • If your host device requires charging, connect a USB-C charger (up to 100W) to the USB-C PD port on the hub.

• HDMI Compatibility: Ensure your host device supports DisplayPort Alt Mode for HDMI output. Without this, the HDMI port will not function.
• Power Delivery: Use a high-quality USB-C charger to ensure stable pass-through charging.
• Data Transfer: For optimal performance, use USB 3.0-compatible devices with the USB-A ports.
• Ethernet Setup: Install necessary drivers if the Ethernet port is not automatically recognized by your operating system.
• Heat Management: The hub may become warm during extended use. This is normal and within safe operating limits.

The UGREEN Revodok Pro 109 can be used to connect an Arduino UNO to a laptop for programming and data transfer. Below is an example of Arduino code for basic LED blinking:

// This code blinks an LED connected to pin 13 of the Arduino UNO.
// Ensure the Arduino is connected to the laptop via the USB-A port on the hub.

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output pin
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. HDMI Output Not Working:

   • Cause: Host device does not support DisplayPort Alt Mode.
   • Solution: Verify that your device supports DisplayPort Alt Mode. Check the device's specifications or contact the manufacturer.

2. USB Devices Not Recognized:
