### 4. Power Distribution Board (PDB) Pins
BATTERY (2-pin header): Connect the battery to these pins. Typically, the order is:
+ POS (positive): Connect to the battery positive wire.
+ NEG (negative): Connect to the battery negative wire.
VCC (multiple 2-pin headers): Connect the VCC wires from the ESCs, FC, and other components to these pins.
GND (multiple 2-pin headers): Connect the GND wires from the ESCs, FC, and other components to these pins.
Connection Structure:
1. Connect the motors to the ESCs, ensuring the correct wire order (A, B, and C).
2. Connect the ESCs to the PDB, ensuring the correct wire order (Signal, Ground, and Power).
3. Connect the FC to the PDB, ensuring the correct wire order (Signal, Ground, and Power).
4. Connect the telemetry modules, GPS, or other serial devices to the FC's UART pins.
5. Connect I2C devices to the FC's I2C pins.
6. Connect the PPM/Sum signal from the receiver to the FC's PPM/Sum pins.
7. Connect the battery to the PDB, ensuring the correct wire order (Positive and Negative).
Important Notes:
Always double-check the pinout and wire connections to avoid damage to the components or the drone.
Ensure proper soldering and insulation to prevent electrical shorts.
Refer to the individual component datasheets and tutorials for specific connection guides and configuration requirements.
Consult the drone's manual and online resources for assembly and setup instructions.

Code Examples

### Example 1: Using the QAV250 with an Arduino-based flight controller

In this example, we will use an Arduino-based flight controller, such as the KK2.1.5, to control the QAV250 drone.

Arduino Code
```c++
#include <KK2.h>

#define MOTOR_PIN_FRONT_LEFT 2
#define MOTOR_PIN_FRONT_RIGHT 3
#define MOTOR_PIN_BACK_LEFT 4
#define MOTOR_PIN_BACK_RIGHT 5

KK2 fc;

void setup() {
  // Initialize the flight controller
  fc.init();
  
  // Set the motor pins
  fc.setMotorPin(MOTOR_PIN_FRONT_LEFT, MOTOR_PIN_FRONT_RIGHT, MOTOR_PIN_BACK_LEFT, MOTOR_PIN_BACK_RIGHT);
}

void loop() {
  // Read the sensor data
  int roll = fc.getRoll();
  int pitch = fc.getPitch();
  int yaw = fc.getYaw();
  
  // Calculate the motor speeds
  int motorSpeeds[4];
  motorSpeeds[0] = roll + pitch + yaw;
  motorSpeeds[1] = roll - pitch + yaw;
  motorSpeeds[2] = -roll + pitch + yaw;
  motorSpeeds[3] = -roll - pitch + yaw;
  
  // Set the motor speeds
  fc.setMotorSpeed(MOTOR_PIN_FRONT_LEFT, motorSpeeds[0]);
  fc.setMotorSpeed(MOTOR_PIN_FRONT_RIGHT, motorSpeeds[1]);
  fc.setMotorSpeed(MOTOR_PIN_BACK_LEFT, motorSpeeds[2]);
  fc.setMotorSpeed(MOTOR_PIN_BACK_RIGHT, motorSpeeds[3]);
  
  delay(20);
}
```
### Example 2: Using the QAV250 with a PX4-based flight controller

In this example, we will use a PX4-based flight controller, such as the PX4FMU, to control the QAV250 drone.

PX4 Configuration

To configure the PX4 flight controller, follow these steps:

1. Connect to the PX4 console using a serial terminal or QGroundControl.
2. Set the vehicle type to `quadrotor` using the command `set VEHICLE_TYPE quadrotor`.
3. Set the motor configuration to `x` configuration using the command `set MOTOR_CONFIG x`.
4. Set the motor speeds to `1200` using the command `set MOTOR_SPEED 1200`.

PX4 Code

To control the drone using PX4, you can use the `px4_command` library to send commands to the flight controller.

C++ Code
```c++
#include <px4_command.h>

int main() {
  // Initialize the PX4 connection
  px4_command conn;
  conn.init();
  
  // Arm the drone
  conn.arm();
  
  // Set the drone to hover mode
  conn.set_mode(MODE_HOVER);
  
  // Set the drone to altitude 10m
  conn.set_altitude(10.0);
  
  // Wait for 10 seconds
  usleep(10000000);
  
  // Land the drone
  conn.land();
  
  return 0;
}
```
