• IoT (Internet of Things) devices
• Industrial automation
• Robotics and motor control
• Data acquisition systems
• Prototyping for consumer electronics
• Educational and research projects

1. Powering the Board:

   • Connect the board to your computer via the USB Type-A to Micro-B cable for power and programming.
   • Alternatively, use an external power supply (7-12V) connected to the VIN pin.

2. Programming the Board:

   • Install the STM32CubeIDE or Arduino IDE (with STM32 core support).
   • Connect the board to your computer via USB.
   • Select the appropriate board and port in your IDE.
   • Write your code and upload it to the board.

3. Connecting Peripherals:

   • Use the Arduino Uno V3 headers for shields or the ST morpho headers for custom peripherals.
   • Ensure proper voltage levels and pin configurations for connected devices.

4. Debugging:

   • Use the ST-LINK/V3 embedded debugger for real-time debugging and programming.

• Ensure the input voltage does not exceed the specified range (7-12V for VIN).
• Avoid drawing excessive current from the GPIO pins (maximum 25 mA per pin).
• Use proper decoupling capacitors when connecting external components to reduce noise.
• Always check the pin configuration and alternate functions in the STM32H5 datasheet before use.

Below is an example code to blink an LED connected to pin D13:

// Blink an LED on pin D13 (onboard LED)

// Define the LED pin
const int ledPin = 13;

void setup() {
  // Set the LED pin as an output
  pinMode(ledPin, OUTPUT);
}

void loop() {
  // Turn the LED on
  digitalWrite(ledPin, HIGH);
  delay(1000); // Wait for 1 second

  // Turn the LED off
  digitalWrite(ledPin, LOW);
  delay(1000); // Wait for 1 second
}

1. Board Not Detected by IDE:

   • Ensure the USB cable is properly connected and functional.
   • Install the required drivers for the ST-LINK/V3 debugger.
   • Verify that the correct board and port are selected in the IDE.

2. Code Upload Fails:

   • Check the power supply and ensure the board is powered on.
   • Press the reset button on the board and try uploading again.
   • Ensure no other application is using the COM port.

3. Peripherals Not Working:

   • Double-check the pin connections and configurations.
   • Verify that the peripheral is compatible with the board's voltage levels.
   • Use a multimeter to check for continuity and proper power supply.
