• Industrial control systems
• Robotics and automation
• Wearable devices
• Prototyping for consumer electronics
• Educational and research projects

The STM32 NUCLEO-F412ZG features multiple pin headers, including Arduino Uno R3-compatible headers and ST morpho connectors. Below is a summary of the pin configuration:

1. Powering the Board:

   • Connect the board to your computer via the USB Mini-B cable for power and programming.
   • Alternatively, supply power through the VIN pin (7V-12V) or the 5V pin.

2. Programming the Board:

   • Use the integrated ST-LINK/V2-1 debugger/programmer to upload code.
   • Compatible with STM32CubeIDE, Keil MDK, IAR Embedded Workbench, and Arduino IDE.

3. Connecting Peripherals:

   • Use the Arduino Uno R3 headers for shields and modules.
   • Use the ST morpho connectors for advanced peripherals and GPIO access.

4. Running the Code:

   • After uploading the code, the board will automatically reset and execute the program.

• Ensure the input voltage does not exceed the specified range to avoid damaging the board.
• Use decoupling capacitors when connecting external components to reduce noise.
• Avoid shorting pins or connecting incompatible voltage levels to GPIOs.
• Use the ST-LINK utility or STM32CubeProgrammer for firmware updates and debugging.

Below is an example of how to blink an LED connected to pin D13 using the Arduino IDE:

// Blink an LED on pin D13 of the STM32 NUCLEO-F412ZG

void setup() {
  pinMode(13, OUTPUT); // Set pin D13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. Board Not Detected by Computer:

   • Ensure the USB cable is properly connected and functional.
   • Check if the ST-LINK driver is installed on your computer.

2. Code Upload Fails:

   • Verify that the correct board and port are selected in the IDE.
   • Ensure no other application is using the ST-LINK interface.

3. GPIO Pins Not Responding:

   • Check the pin configuration in your code.
   • Ensure the pins are not being used by other peripherals.

4. Power Issues:

   • Confirm the input voltage is within the specified range.
   • Check for loose connections or damaged components.
