The Arch V1.1 features a standard pinout for easy integration with other components. Below is the pin configuration:

The Arch V1.1 is designed for ease of use in prototyping and development. Follow the steps below to get started:

1. Power the Board: Connect the Arch V1.1 to your computer or a power source using a micro-USB cable. The board operates at 3.3V but can accept 5V input via USB.
2. Connect Components: Use the digital and analog pins to connect sensors, actuators, or other peripherals. Ensure proper pin mapping based on the pin configuration table.
3. Program the Board: The Arch V1.1 supports drag-and-drop programming. Simply copy the compiled firmware (e.g., .bin file) to the board's USB storage.
4. Test the Circuit: Once the firmware is uploaded, test the circuit functionality by observing the connected components.

• Voltage Levels: Ensure that all connected components operate within the 3.3V logic level to avoid damage.
• Pin Usage: Avoid exceeding the current limits of the I/O pins (maximum 4mA per pin).
• Firmware Updates: Regularly check for firmware updates from Seeed Studio to ensure compatibility and performance.
• Debugging: Use the UART interface for debugging and monitoring serial data.

The Arch V1.1 can be programmed using the Arduino IDE. Below is an example code snippet to read an analog sensor connected to pin A0 and output the value via the serial monitor:

// Example code for Arch V1.1
// Reads an analog value from pin A0 and prints it to the serial monitor

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
}

void loop() {
  int sensorValue = analogRead(A0); // Read the analog value from pin A0
  Serial.print("Sensor Value: ");   // Print a label for the value
  Serial.println(sensorValue);     // Print the sensor value
  delay(500);                       // Wait for 500ms before the next reading
}

1. Board Not Recognized by Computer:

   • Ensure the USB cable is properly connected and functional.
   • Verify that the correct drivers are installed for the Arch V1.1.

2. Firmware Not Uploading:

   • Check that the firmware file is in the correct format (e.g., .bin).
   • Ensure the board is in programming mode by resetting it if necessary.

3. Components Not Responding:

   • Double-check the wiring and connections to the pins.
   • Verify that the components are compatible with the 3.3V logic level.

4. Serial Monitor Not Displaying Data:

   • Confirm that the correct COM port is selected in the Arduino IDE.
   • Ensure the baud rate in the Serial Monitor matches the Serial.begin() setting.

• Reset the Board: If the board becomes unresponsive, press the reset button to restart it.
• Check Power Supply: Ensure the board is receiving adequate power from the USB connection.
• Inspect Connections: Use a multimeter to verify continuity and proper voltage levels at the pins.
• Consult Documentation: Refer to the official Seeed Studio documentation for additional support and resources.

By following this guide, you can effectively utilize the Arch V1.1 for your prototyping and development needs.
