How to Use Flipsky Dual 75100 With Aluminum PCB: Examples, Pinouts, and Specs

The Flipsky Dual 75100 is a high-performance dual motor controller specifically designed for electric skateboards, scooters, and other electric vehicles. It features an aluminum PCB, which enhances heat dissipation and ensures durability under high-power operation. This motor controller is capable of driving two brushless DC (BLDC) motors simultaneously, making it an ideal choice for applications requiring precise motor control and high efficiency.

• Electric skateboards and longboards
• Electric scooters and bikes
• Robotics and automation systems
• DIY electric vehicle projects
• High-performance RC vehicles

The Flipsky Dual 75100 is engineered to deliver robust performance and reliability. Below are its key technical specifications:

The Flipsky Dual 75100 features multiple connectors for power, motor, and communication. Below is the pin configuration:

1. Power Connection: Connect the VBAT+ and VBAT- terminals to a compatible battery pack (14V-84V). Ensure the battery can supply sufficient current for your application.
2. Motor Connection: Connect the three-phase wires of each motor to the corresponding M1A, M1B, M1C (for Motor 1) and M2A, M2B, M2C (for Motor 2) terminals.
3. Control Signals: Use the UART, CAN, or PWM pins to send control signals to the motor controller. For Arduino-based projects, UART is commonly used.
4. Cooling: Ensure proper ventilation or additional cooling, as the controller may generate heat during operation despite the aluminum PCB.

• Voltage Compatibility: Ensure the battery voltage is within the supported range (14V-84V). Exceeding this range may damage the controller.
• Current Limits: Configure the current limits in the firmware to match your motor and battery specifications.
• Firmware Configuration: Use the VESC Tool software to configure the controller for your specific motors and application.
• Wiring: Double-check all connections before powering on the system to avoid short circuits or damage.
• Heat Management: While the aluminum PCB improves heat dissipation, consider adding a heatsink or active cooling for high-power applications.

Below is an example of controlling the Flipsky Dual 75100 using UART communication with an Arduino UNO:

#include <SoftwareSerial.h>

// Define RX and TX pins for UART communication
#define RX_PIN 10  // Arduino pin connected to UART_TX of the controller
#define TX_PIN 11  // Arduino pin connected to UART_RX of the controller

// Initialize SoftwareSerial for UART communication
SoftwareSerial motorController(RX_PIN, TX_PIN);

void setup() {
  // Start serial communication with the motor controller
  motorController.begin(115200); // Default baud rate for the controller
  Serial.begin(9600); // For debugging via Serial Monitor

  // Send an example command to the motor controller
  // Replace with actual commands based on your application
  motorController.write("start_motor_1"); 
  Serial.println("Motor 1 start command sent.");
}

void loop() {
  // Example: Read data from the motor controller
  if (motorController.available()) {
    String response = motorController.readString();
    Serial.println("Controller Response: " + response);
  }

  // Add your motor control logic here
}

Note: Replace "start_motor_1" with the actual command format supported by the Flipsky Dual 75100. Refer to the VESC Tool documentation for command details.

1. Motor Not Spinning

   • Cause: Incorrect wiring or configuration.
   • Solution: Verify motor phase connections and ensure the controller is configured correctly using the VESC Tool.

2. Overheating

   • Cause: Insufficient cooling or excessive current draw.
   • Solution: Add a heatsink or active cooling. Reduce the current limits in the firmware.

3. No Communication with Controller

   • Cause: Incorrect UART, CAN, or PWM connections.
   • Solution: Check the wiring and ensure the correct baud rate or protocol is used.

4. Controller Not Powering On

   • Cause: Insufficient battery voltage or loose connections.
   • Solution: Ensure the battery voltage is within the supported range and check all power connections.

Q: Can I use the Flipsky Dual 75100 with a single motor?
A: Yes, you can use the controller with a single motor by connecting it to either Motor 1 or Motor 2 terminals. Ensure the unused motor terminals are left unconnected.

Q: What software is required to configure the controller?
A: The Flipsky Dual 75100 is compatible with the VESC Tool software, which allows you to configure motor parameters, current limits, and control modes.

Q: Is the controller waterproof?
A: No, the controller is not waterproof. It is recommended to protect it from water and moisture during use.

Q: Can I use this controller for hub motors?
A: Yes, the Flipsky Dual 75100 supports hub motors as long as they are brushless DC (BLDC) motors and within the voltage and current limits of the controller.
