The Spark Max Engine Controller features a variety of input and output pins for flexible integration. Below is the pinout description:

The Spark Max Engine Controller is designed for ease of use while offering advanced features for experienced users. Follow the steps below to integrate it into your project:

1. Power Connection: Connect the VIN+ and VIN- pins to a power source within the 5.5V to 24V range.
2. Motor Connection: Attach the motor leads to the M+ and M- terminals, ensuring correct polarity.
3. Control Signal: Choose a control method (e.g., PWM, CAN, or Analog) and connect the appropriate pins.
4. Encoder Connection (Optional): If using an encoder, connect the encoder's A, B, and I signals to the ENC_A, ENC_B, and ENC_I pins, respectively.

• Ensure the input voltage does not exceed 24V to avoid damaging the controller.
• Use appropriate wire gauges for power and motor connections to handle the current load.
• Securely mount the controller to prevent vibration or movement during operation.
• If using CAN communication, terminate the CAN bus with a 120-ohm resistor at both ends.

The Spark Max Engine Controller can be controlled via PWM signals from an Arduino UNO. Below is an example code snippet to control motor speed:

// Include necessary libraries
#include <Servo.h> // Library to generate PWM signals

// Define the PWM pin connected to the Spark Max
const int pwmPin = 9;

// Create a Servo object to generate PWM
Servo motorController;

void setup() {
  // Attach the PWM pin to the Servo object
  motorController.attach(pwmPin);
  
  // Set initial motor speed to 0 (stopped)
  motorController.writeMicroseconds(1500); 
  // 1500 µs is typically the neutral signal for motor controllers
}

void loop() {
  // Example: Gradually increase motor speed
  for (int speed = 1500; speed <= 2000; speed += 10) {
    motorController.writeMicroseconds(speed); // Send PWM signal
    delay(100); // Wait for 100 ms
  }

  // Example: Gradually decrease motor speed
  for (int speed = 2000; speed >= 1500; speed -= 10) {
    motorController.writeMicroseconds(speed); // Send PWM signal
    delay(100); // Wait for 100 ms
  }
}

• Calibrate the motor controller using the manufacturer's software before use.
• Use proper heat dissipation methods, such as a heatsink or fan, for high-current applications.
• Regularly inspect connections to ensure they are secure and free of corrosion.

1. Motor Not Spinning

   • Cause: Incorrect wiring or insufficient power supply.
   • Solution: Verify all connections and ensure the power supply meets the voltage and current requirements.

2. Overheating

   • Cause: Prolonged operation at high current or inadequate cooling.
   • Solution: Add a heatsink or fan to improve heat dissipation.

3. Erratic Motor Behavior

   • Cause: Noise in the control signal or incorrect encoder wiring.
   • Solution: Use shielded cables for control signals and double-check encoder connections.

4. No Communication via CAN

   • Cause: Missing or incorrect termination resistors.
   • Solution: Ensure 120-ohm resistors are installed at both ends of the CAN bus.
