6. Setup Instructions

6.1. Software Installation (Arduino IDE)

1. Download and install the latest version of the Arduino IDE from the official Arduino website (www.arduino.cc/en/software).
2. Open the Arduino IDE.
3. Go to Tools > Board > Board Manager....
4. Search for "SparkFun AVR Boards" and install the package. This package includes support for the Pro Micro.
5. After installation, go to Tools > Board and select "SparkFun Pro Micro". Ensure "ATmega32U4 (5V, 16MHz)" is selected as the processor.

6.2. Connecting the Module

1. Connect the Teyleten Robot Pro Micro module to your computer using a Type-C USB cable.
2. The module should be recognized by your operating system, and a new COM port (Windows) or /dev/ttyACM* (Linux/macOS) should appear.
3. In the Arduino IDE, go to Tools > Port and select the newly appeared serial port.

Power Supply: The board can be powered via the USB Type-C port. If supplying unregulated power, connect it to the "RAW" pin. The recommended unregulated power supply is 6-7V, not exceeding 9V. Do not connect unregulated power to the VCC pin.

7. Operating Instructions

7.1. Uploading a Sketch

1. Open an example sketch in the Arduino IDE (e.g., File > Examples > 01.Basics > Blink).
2. Ensure the correct board (SparkFun Pro Micro, ATmega32U4 5V/16MHz) and port are selected under the Tools menu.
3. Click the "Upload" button (right arrow icon) in the Arduino IDE. The IDE will compile the sketch and upload it to the Pro Micro module.
4. During upload, the RX and TX LEDs on the board may flash. Upon successful upload, the sketch will begin running.

7.2. Using Digital I/O and Analog Pins

• Digital I/O: Use pinMode(), digitalWrite(), and digitalRead() functions to control digital pins.
• PWM: Pins D3, D5, D6, D9, D10 are PWM capable. Use analogWrite() for PWM output.
• Analog Input: Pins A0-A3 can be used for analog input. Use analogRead() to read analog values.

8. Maintenance and Care

• Keep the module in a dry environment to prevent moisture damage.
• Avoid exposing the board to extreme temperatures or direct sunlight.
• Handle the board by its edges to prevent electrostatic discharge (ESD) damage to components.
• Ensure proper power supply connections to avoid overvoltage or reverse polarity damage.
• Clean the board gently with a soft, dry brush if dust accumulates. Do not use liquids.

9. Troubleshooting

Issue: Module not recognized by computer / No power LED.

Solution 1: Ensure the USB Type-C cable is fully inserted and functional. Try a different cable or USB port.

Solution 2: Verify that the correct drivers are installed. For Arduino IDE, ensure the "SparkFun AVR Boards" package is installed.

Solution 3: If the board was previously programmed, it might be in a state where it doesn't immediately enumerate as a serial device. Try pressing the reset button twice quickly to enter the bootloader mode, then attempt to upload a sketch.

Issue: Sketch upload fails.

Solution 1: Check if the correct board ("SparkFun Pro Micro") and port are selected in the Arduino IDE's Tools menu.

Solution 2: Ensure no other applications are using the serial port.

Solution 3: If you encounter "programmer not responding" errors, try pressing the reset button on the Pro Micro just before the upload process starts (when the IDE displays "Uploading...").

Issue: External components not working as expected.

Solution 1: Double-check your wiring against the pinout diagram (Section 5).

Solution 2: Verify that your external components are receiving the correct voltage and current. Ensure the Pro Micro's power output is sufficient.

Solution 3: Review your code for logical errors or incorrect pin assignments.
