The PQ12 Cable Adapter features a JST 3-pin connector on one end and a standard 3-pin servo connector on the other. The pinout is as follows:

The PQ12 Cable Adapter is straightforward to use and can be integrated into various electronic systems. Follow the steps below to use the adapter effectively:

1. Identify the Connectors: Determine which end of the adapter connects to your device (e.g., actuator, sensor) and which end connects to your control system (e.g., microcontroller).
2. Connect the JST 3-Pin Connector: Plug the JST 3-pin connector into the corresponding port on your device. Ensure the pin alignment matches the pinout described above.
3. Connect the Servo Connector: Attach the standard 3-pin servo connector to your control system or power source.
4. Verify Connections: Double-check all connections to ensure proper alignment and secure fit.
5. Power On the System: Once all connections are secure, power on your system to begin operation.

• Voltage Compatibility: Ensure the voltage supplied to the adapter matches the requirements of your connected device (5V to 12V DC).
• Signal Integrity: Use short, high-quality cables to minimize signal degradation.
• Avoid Overloading: Do not exceed the current rating of 2A to prevent damage to the adapter or connected devices.
• Secure Connections: Ensure all connectors are firmly seated to avoid intermittent connections.

The PQ12 Cable Adapter can be used to connect an actuator to an Arduino UNO. Below is an example code snippet to control an actuator using the adapter:

#include <Servo.h> // Include the Servo library

Servo actuator; // Create a Servo object to control the actuator

void setup() {
  actuator.attach(9); // Attach the actuator to pin 9 on the Arduino
  // Ensure the PQ12 Cable Adapter is connected to the actuator and Arduino
}

void loop() {
  actuator.write(0); // Move the actuator to position 0
  delay(1000);       // Wait for 1 second
  actuator.write(90); // Move the actuator to position 90
  delay(1000);       // Wait for 1 second
  actuator.write(180); // Move the actuator to position 180
  delay(1000);       // Wait for 1 second
}

1. Device Not Responding:

   • Cause: Loose or incorrect connections.
   • Solution: Verify all connections and ensure proper pin alignment.

2. Signal Interference:

   • Cause: Long or poor-quality cables.
   • Solution: Use shorter, shielded cables to reduce interference.

3. Overheating:

   • Cause: Exceeding the current rating of 2A.
   • Solution: Ensure the connected device does not draw more than 2A.

4. Voltage Mismatch:

   • Cause: Supplying incorrect voltage to the adapter.
   • Solution: Verify the voltage requirements of your device and ensure the power source matches.

• Use a multimeter to check voltage and continuity across the adapter.
• Test the adapter with a different device to rule out issues with the connected device.
• Refer to the device's datasheet for specific voltage and current requirements.

By following this documentation, users can effectively integrate the PQ12 Cable Adapter into their projects and troubleshoot common issues with ease.
