The LED AxaCube is designed to deliver optimal performance while maintaining a compact form factor. Below are the key technical specifications:

The LED AxaCube has two pins for electrical connections. The table below describes the pin configuration:

1. Power Supply: Ensure the power supply provides a voltage between 3.0V and 3.3V. Exceeding this range may damage the LED.
2. Current Limiting Resistor: To prevent overcurrent, use a resistor in series with the LED. Calculate the resistor value using Ohm's Law: [ R = \frac{V_{supply} - V_{forward}}{I_{forward}} ] For example, with a 5V supply and a forward voltage of 3.0V, and a desired current of 20mA: [ R = \frac{5V - 3.0V}{0.02A} = 100 , \Omega ]
3. Connection: Connect the Anode (Pin 1) to the positive terminal of the power supply through the resistor. Connect the Cathode (Pin 2) to the ground.

The LED AxaCube can be easily controlled using an Arduino UNO. Below is an example of how to blink the LED:

// Define the pin connected to the LED AxaCube
const int ledPin = 9; // Pin 9 is used for PWM control

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
}

• Heat Management: Although the AxaCube is energy-efficient, prolonged use at maximum current may generate heat. Ensure proper ventilation or heat dissipation if used in enclosed spaces.
• Polarity: Always connect the Anode to the positive voltage and the Cathode to ground. Reversing the polarity may damage the LED.
• Resistor Selection: Always use an appropriate current-limiting resistor to prevent overdriving the LED.

1. LED Does Not Light Up

   • Cause: Incorrect polarity or loose connections.
   • Solution: Verify that the Anode is connected to the positive voltage and the Cathode to ground. Check all connections for stability.

2. LED Flickers

   • Cause: Insufficient power supply or loose connections.
   • Solution: Ensure the power supply provides a stable voltage within the operating range. Check for secure connections.

3. LED Burns Out Quickly

   • Cause: Excessive current due to the absence of a current-limiting resistor.
   • Solution: Always use a resistor in series with the LED to limit the current.

4. LED is Dim

   • Cause: Insufficient current or incorrect resistor value.
   • Solution: Recalculate the resistor value to ensure the LED receives the recommended current (20mA).

Q: Can I use the LED AxaCube with a 12V power supply?
A: Yes, but you must use a resistor to drop the voltage to the operating range of 3.0V to 3.3V. Alternatively, use a voltage regulator.

Q: Is the LED AxaCube waterproof?
A: No, the AxaCube is not waterproof. For outdoor or wet environments, use a protective enclosure.

Q: Can I control the brightness of the LED AxaCube?
A: Yes, you can control the brightness using Pulse Width Modulation (PWM) from a microcontroller like an Arduino.

Q: What is the maximum current the LED AxaCube can handle?
A: The maximum current is 30mA. However, for optimal performance and longevity, it is recommended to operate at 20mA.

By following this documentation, you can effectively integrate the LED AxaCube into your projects and ensure reliable performance.
