• A1: Yes, the PDB-XT60 supports 2-6S LiPo batteries, including 4S (14.8V).

Q2: What is the maximum current the PDB-XT60 can handle?

• A2: The PDB-XT60 can handle a continuous current of 120A and a peak current of 160A for 10 seconds.

Q3: How do I connect multiple ESCs to the PDB-XT60?

• A3: Solder the power wires of each ESC to the designated ESC output pads on the PDB. Ensure secure connections.

Q4: Can I use the BEC outputs to power my flight controller?

• A4: Yes, the BEC outputs are designed to provide regulated power to low-current devices like flight controllers.

5. Example Code for Arduino UNO

While the PDB-XT60 itself does not directly interface with an Arduino UNO, it can be used to power an Arduino UNO in a drone or RC vehicle setup. Below is an example code to control an ESC connected to an Arduino UNO:

#include <Servo.h>

// Create a Servo object to control the ESC
Servo esc;

void setup() {
  // Attach the ESC to pin 9 on the Arduino
  esc.attach(9);
  
  // Initialize the ESC with a low signal
  esc.writeMicroseconds(1000);
  
  // Wait for the ESC to initialize
  delay(2000);
}

void loop() {
  // Gradually increase the speed of the motor
  for (int speed = 1000; speed <= 2000; speed += 10) {
    esc.writeMicroseconds(speed);
    delay(20);
  }
  
  // Gradually decrease the speed of the motor
  for (int speed = 2000; speed >= 1000; speed -= 10) {
    esc.writeMicroseconds(speed);
    delay(20);
  }
}

This code demonstrates how to control an ESC using an Arduino UNO. Ensure the ESC is connected to the PDB-XT60 and the Arduino is powered appropriately.

By following this documentation, users can effectively utilize the PDB-XT60 in their projects, ensuring reliable power distribution and optimal performance.
