The Grove Base Shield V2 is designed to be compatible with most Arduino boards, including the Arduino UNO, Mega, and Leonardo. Below are the key technical details:

The Grove Base Shield V2 features multiple Grove ports, each with a specific function. Below is a breakdown of the ports and their pin configurations:

The Grove Base Shield V2 is designed to simplify the process of connecting Grove modules to an Arduino board. Follow the steps below to use the shield effectively:

1. Attach the Shield: Plug the Grove Base Shield V2 onto your Arduino board. Ensure the pins are aligned correctly.
2. Select Voltage: Use the onboard jumper to select the operating voltage (3.3V or 5V) based on the requirements of your Grove modules.
3. Connect Grove Modules: Plug Grove modules into the appropriate ports (Digital, Analog, UART, or I2C) on the shield.

1. Install Arduino IDE: Download and install the Arduino IDE from Arduino's official website.
2. Install Grove Libraries: Many Grove modules require specific libraries. Install these libraries via the Arduino Library Manager or from Seeed Studio's GitHub repository.
3. Write or Load Code: Write your own code or use example sketches provided by Seeed Studio.

Below is an example of how to use the Grove Base Shield V2 with a Grove Temperature Sensor connected to port A0:

// Include the Grove library for the temperature sensor
#include <Grove_Temperature_And_Humidity_Sensor.h>

// Define the analog pin where the sensor is connected
const int tempSensorPin = A0;

void setup() {
  // Initialize serial communication for debugging
  Serial.begin(9600);
  Serial.println("Grove Temperature Sensor Example");
}

void loop() {
  // Read the analog value from the temperature sensor
  int sensorValue = analogRead(tempSensorPin);

  // Convert the analog value to a temperature in Celsius
  float voltage = sensorValue * (5.0 / 1023.0); // Convert to voltage
  float temperatureC = (voltage - 0.5) * 100.0; // Convert to Celsius

  // Print the temperature to the Serial Monitor
  Serial.print("Temperature: ");
  Serial.print(temperatureC);
  Serial.println(" °C");

  // Wait for 1 second before the next reading
  delay(1000);
}

• Always check the voltage requirements of your Grove modules before connecting them.
• Use the I2C port for modules that require I2C communication, such as OLED displays or IMUs.
• Avoid connecting multiple modules to the same port unless explicitly supported.

1. No Data from Grove Module

   • Cause: Incorrect port connection or missing library.
   • Solution: Verify the module is connected to the correct port and install the required library.

2. Arduino Not Recognized by Computer

   • Cause: Faulty USB cable or missing drivers.
   • Solution: Replace the USB cable and ensure the Arduino drivers are installed.

3. Incorrect Sensor Readings

   • Cause: Wrong voltage selection or loose connections.
   • Solution: Check the voltage jumper setting and ensure all connections are secure.

1. Can I use the Grove Base Shield V2 with a Raspberry Pi?

   • No, the Grove Base Shield V2 is designed specifically for Arduino boards. For Raspberry Pi, use the GrovePi+.

2. How many Grove modules can I connect simultaneously?

   • You can connect up to 16 modules, depending on the type of ports and modules used.

3. Is the shield compatible with 3.3V-only Arduino boards?

   • Yes, the shield supports both 3.3V and 5V operation. Use the jumper to select the appropriate voltage.

By following this documentation, you can effectively use the Grove Base Shield V2 to simplify your prototyping and development process.
