Pin Configuration

Brushless Water Pump Component Documentation
Pinout Description
The Brushless Water Pump component has a total of 6 pins, which are used to control and power the pump. Here's a detailed explanation of each pin, point by point:
1. VCC (Pin 1)
Function: Power supply input
Description: This pin is used to connect the positive power supply (typically 12V or 24V) to the pump. Ensure the voltage rating matches the pump's specifications.
Connection: Connect to a suitable power source (e.g., a battery, wall adapter, or power supply module) using a wire or PCB track.
2. GND (Pin 2)
Function: Ground connection
Description: This pin is used to connect the negative power supply (ground) to the pump. Ensure a secure and low-impedance connection to the power source's ground.
Connection: Connect to the power source's ground (e.g., a battery's negative terminal, wall adapter's ground, or power supply module's ground) using a wire or PCB track.
3. PWM (Pin 3)
Function: Pulse Width Modulation input
Description: This pin is used to control the pump's speed using a PWM signal from a microcontroller or dedicated PWM generator. The PWM frequency typically ranges from 20 kHz to 100 kHz.
Connection: Connect to a microcontroller's PWM output pin (e.g., Arduino's Timer pin) or a dedicated PWM generator module using a wire or PCB track.
4. DIR (Pin 4)
Function: Direction control input
Description: This pin is used to control the direction of the pump's rotation. A logical HIGH (VCC) sets the pump to rotate clockwise, while a logical LOW (GND) sets it to rotate counterclockwise.
Connection: Connect to a microcontroller's digital output pin (e.g., Arduino's Digital pin) or a switch/signal generator module using a wire or PCB track.
5. EN (Pin 5)
Function: Enable input
Description: This pin is used to enable or disable the pump. A logical HIGH (VCC) enables the pump, while a logical LOW (GND) disables it.
Connection: Connect to a microcontroller's digital output pin (e.g., Arduino's Digital pin) or a switch/signal generator module using a wire or PCB track.
6. SDA (Pin 6)
Function: Serial data input (optional)
Description: This pin is used for optional serial communication with the pump's internal microcontroller (if available). It allows for monitoring or configuring the pump's parameters, such as speed, direction, or fault detection.
Connection: Connect to a microcontroller's serial communication pin (e.g., Arduino's SDA pin) or a dedicated serial communication module using a wire or PCB track. If not used, this pin can be left unconnected.
Connection Structure
When connecting the pins, ensure the following structure is maintained:
Pin 1 (VCC) to Power Source Positive Terminal
Pin 2 (GND) to Power Source Ground Terminal
Pin 3 (PWM) to Microcontroller's PWM Output Pin or Dedicated PWM Generator Module
Pin 4 (DIR) to Microcontroller's Digital Output Pin or Switch/Signal Generator Module
Pin 5 (EN) to Microcontroller's Digital Output Pin or Switch/Signal Generator Module
Pin 6 (SDA) to Microcontroller's Serial Communication Pin or Dedicated Serial Communication Module (optional)
Important Notes
Ensure the power supply voltage and current ratings match the pump's specifications to avoid damage or overheating.
Use suitable wire gauges and connectors to minimize power losses and ensure reliable connections.
Implement proper noise reduction and filtering techniques to minimize electromagnetic interference (EMI) and ensure reliable operation.
Consult the pump's datasheet and manufacturer's guidelines for specific connection requirements and precautions.

const int pumpSpeed = 50;  // Initial pump speed (0-100%)

void setup() {
  pinMode(pwmPin, OUTPUT);
}

void loop() {
  analogWrite(pwmPin, pumpSpeed);  // Set pump speed using PWM
  delay(1000);  // Wait 1 second
}
```

pump_address = 0x1A

# Initialize I2C bus
bus = smbus.SMBus(i2c_bus)

# Set pump speed using I2C (0-100%)
def set_pump_speed(speed):
  bus.write_byte_data(pump_address, 0x01, speed)

# Set initial pump speed
set_pump_speed(50)
```

### Example 3: ESP32-based UART Control

This example demonstrates how to control the Brushless Water Pump using an ESP32 board and UART communication.

```c
#include <WiFi.h>
#include <SoftwareSerial.h>

// UART pins on ESP32
#define TX_PIN 17
#define RX_PIN 16

// Initialize UART interface
SoftwareSerial uart(TX_PIN, RX_PIN);

// Set pump speed using UART (0-100%)
void set_pump_speed(uint8_t speed) {
  uart.print("SET_SPEED ");
  uart.print(speed);
  uart.println();
}

// Set initial pump speed
set_pump_speed(50);
```

These code examples illustrate how to control the Brushless Water Pump using different communication interfaces and microcontrollers. The pump's speed can be adjusted by modifying the PWM signal, I2C command, or UART command to achieve the desired flow rate and pressure head.
