Frequently Asked Questions (FAQ)

• Does this board support Micropython?
  Yes, WeAct Studio provides Micropython firmware builds specifically for this board, making it easy to script hardware interactions.
• Is the OV7725 camera included in the price?
  Yes, this is the full kit which includes the STM32H7 board, the 0.96" TFT LCD, and the OV7725 Camera module.
• What is the maximum resolution of the OV7725 camera?
  The OV7725 has a native resolution of 640x480 (VGA).
• Can I use the Arduino IDE to program this board?
  Yes, via the STM32Duino project. You will need to select the "Generic STM32H7 Series" in the board manager, though functionality may be limited compared to CubeIDE.
• Does it have WiFi or Bluetooth?
  No, the STM32H743 is a microcontroller, not an SoC. For wireless, you would need to interface an ESP8266 or ESP32 module via UART.
• How do I view the camera output?
  The default demo code typically displays the camera feed directly on the attached 0.96" TFT screen.
• What driver does the LCD use?
  The included 0.96" IPS display uses the ST7735 driver IC.
• Can I use a larger display?
  Yes, the board breaks out SPI and LTDC pins (check pinout), allowing you to connect larger displays, provided you write the drivers.
• Is the USB-C port for power only?
  No, the USB-C port supports both power and data (USB OTG FS), allowing the board to act as a USB device (like a keyboard or mouse).
• Do I need an external programmer?
  Yes, you need an ST-Link V2 or V3 to program and debug this board via the SWD header.
• What is the difference between H743 and F405?
  The H743 is significantly faster (480MHz vs 168MHz), has more memory, and includes advanced peripherals like double-precision FPU and Chrom-ART Accelerator.
• Can this run TensorFlow Lite for Microcontrollers?
  Absolutely. The Cortex-M7 core is powerful enough to run quantized TinyML models for keyword spotting or basic gesture recognition.
• Is the pinout compatible with the Blackpill?
  No, the form factor and pinout are different. Always check the pin map provided in the datasheets.
• What voltage regulator is on board?
  It typically uses a robust LDO capable of supplying enough current for the MCU, camera, and screen.
• Does it support an SD Card?
  Yes, there is a micro SD card slot on the bottom of the board wired to the SDIO interface.
• How do I reset the board into DFU mode?
  Hold the Boot0 button, press and release Reset, then release Boot0. The board should appear as a DFU device over USB-C.
• Is the 8MB Flash internal or external?
  The 2MB Flash is internal to the MCU. The kit includes an additional 8MB SPI Flash and 8MB QSPI Flash chip soldered on the board (external).
• Can I power this with a LiPo battery?
  You can connect a 3.7V-5V source to the 5V pin, but ensure your voltage source is stable.
• Does the camera support auto-focus?
  The OV7725 is a fixed-focus lens module, but the lens can often be manually twisted to adjust focus range.
• Is this board suitable for beginners?
  We recommend this for Intermediate to Advanced users. Beginners might find the complexity of the H7 clock tree and peripherals challenging.
