How to Use 1X 12 Position Power Distribution Board PCB007: Examples, Pinouts, and Specs

The 1X 12 Position Power Distribution Board PCB007 by Evemodel is a versatile and efficient power distribution solution designed to manage and distribute electrical power to multiple circuits. With 12 connection positions, this board is ideal for organizing power connections in complex electronic projects, ensuring a clean and reliable power supply to various components.

• Model railroads and train layouts
• Robotics and automation systems
• LED lighting arrays
• DIY electronics projects requiring multiple power connections
• Prototyping and testing circuits

The following table outlines the key technical details of the PCB007 power distribution board:

The PCB007 features 12 screw terminal positions, divided into two rows for easy connection. Below is the pin configuration:

Each terminal is clearly labeled on the board for quick identification during installation.

1. Power Input: Connect the main power source (e.g., a DC power supply) to one of the positive (+) and negative (-) terminals on the board.
2. Power Distribution: Use the remaining terminals to connect individual circuits or components that require power. Ensure proper polarity when connecting devices.
3. Securing Connections: Tighten the screw terminals securely to avoid loose connections, which can lead to power interruptions or short circuits.
4. Mounting: Use the mounting holes to secure the board to a stable surface, such as a project enclosure or a wooden base.

• Voltage and Current Limits: Ensure the total voltage and current do not exceed the board's maximum ratings (24V DC and 15A).
• Wire Gauge: Use appropriate wire gauges for your connections. For high-current applications, use thicker wires to minimize resistance and heat.
• Polarity: Double-check the polarity of all connections to prevent damage to your components.
• Short Circuit Protection: Consider adding a fuse or circuit breaker to your power supply to protect the board and connected devices from short circuits.

The PCB007 can be used to distribute power to an Arduino UNO and other peripherals. Below is an example setup:

1. Connect a 12V DC power supply to the PCB007.
2. Use one positive and one negative terminal to power the Arduino UNO via its VIN and GND pins.
3. Use other terminals to power additional components, such as sensors or motors.

// This code demonstrates how to blink an LED connected to an Arduino UNO
// powered via the PCB007 power distribution board.

const int ledPin = 13; // Pin connected to the LED

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

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

1. Loose Connections:

   • Issue: Devices intermittently lose power.
   • Solution: Ensure all screw terminals are tightened securely. Check for frayed wires.

2. Overheating:

   • Issue: The board or wires become hot during operation.
   • Solution: Verify that the total current does not exceed 15A. Use thicker wires for high-current applications.

3. No Power to Connected Devices:

   • Issue: Devices connected to the board do not power on.
   • Solution: Check the polarity of the connections and ensure the power source is functioning correctly.

4. Short Circuit:

   • Issue: Sparks or power supply shuts off.
   • Solution: Inspect all connections for exposed wires or incorrect polarity. Add a fuse for protection.

Q1: Can I use the PCB007 with an AC power source?
A1: No, the PCB007 is designed for DC power only. Using AC power may damage the board and connected devices.

Q2: What is the maximum wire size the terminals can accommodate?
A2: The screw terminals can accommodate wires up to 14 AWG.

Q3: Can I use this board for high-power applications like motors?
A3: Yes, as long as the total current does not exceed 15A. For motors with high inrush currents, consider using a relay or motor driver.

Q4: Is the board protected against reverse polarity?
A4: No, the PCB007 does not have built-in reverse polarity protection. Always double-check your connections.

By following this documentation, you can effectively utilize the 1X 12 Position Power Distribution Board PCB007 in your projects, ensuring reliable and organized power distribution.
