Frequently Asked Questions (FAQ)

• Does this board support MicroPython?
  Yes, the STM32H7 series is very popular in the MicroPython community. You will need to flash the firmware onto the 8MB QSPI flash.
• Can I use the Arduino IDE with this board?
  Yes, via the STM32Duino core. However, for advanced camera features, STM32CubeIDE or MicroPython is recommended.
• Is the camera high definition?
  No, the OV7725 is a VGA (640x480) camera. It is optimized for speed and machine vision processing, not high-res photography.
• Does it have WiFi or Bluetooth?
  No, this is a pure high-performance MCU board. You would need to add an ESP8266 or similar module for wireless connectivity.
• Why does it have only 128KB internal flash?
  The H750 is a "Value Line" chip. It relies on the onboard 8MB QSPI external flash for storing large program code and assets, which is seamlessly mapped in memory.
• Can I run OpenMV firmware on this?
  This board hardware is very similar to early OpenMV cams. Ported versions of the firmware exist for this specific board (often called the "Source copy" or generic port).
• What is the maximum frame rate of the camera?
  The OV7725 can theoretically hit 60 FPS at VGA resolution, though your processing logic will determine the actual effective frame rate.
• Does the USB-C port support power and data?
  Yes, it powers the board and acts as a Virtual COM Port or DFU interface for programming.
• Do I need an external ST-Link programmer?
  Not necessarily. You can program it via USB-C using the DFU (Device Firmware Upgrade) mode. However, an ST-Link V2 is recommended for step-by-step debugging.
• Is the pin header soldered?
  No, headers are usually included but unsoldered, giving you the flexibility to solder wires directly or use the headers.
• What is the resolution of the screen?
  The 0.96" IPS display has a resolution of 160x80 pixels.
• Can I use a battery to power it?
  Yes, you can supply 3.3V-5V to the respective power pins (5V or 3.3V and GND).
• Is the logic level 5V tolerant?
  Most pins on the STM32H7 are NOT 5V tolerant. Stick to 3.3V logic to avoid damaging the chip.
• How do I reset the board?
  There is a dedicated NRST button on the board.
• Does it have an SD card slot?
  This specific Core Board revision typically has a footprint for a MicroSD card on the bottom, or relies on the 8MB QSPI flash. (Check physical board upon arrival as revisions vary).
• What driver does the LCD use?
  The 0.96" IPS display usually uses the ST7735S driver chip.
• Can I use this for audio processing?
  Yes, the Cortex-M7 has powerful DSP instructions and I2S interfaces suitable for audio analysis.
• Is this board suitable for beginners?
  It is an "Intermediate to Advanced" board. Total beginners might find the complexity of the H7 clock tree overwhelming compared to an Arduino Uno.
• What is the Key button for?
  It is a programmable user button connected to a specific GPIO (usually PA0), useful for testing inputs.
• Why is my code disappearing after restart?
  If using C++, ensure your linker script places the code in the correct memory bank (Internal Flash vs External QSPI). If using MicroPython, ensure you saved main.py to the filesystem.
