SPECIFICATIONS

Product Information

• Processor: ARM Cortex M7, with a maximum operating frequency of 480MHz, equipped with FPU floating-point unit, and has complete DSP instructions and Memory Protection Unit (MPU).

• Memory: 128KB Flash Program Memory; 8MB SPI Flash, 8MB QSPI Flash (programmable); 1024KB RAM, 192KB TCM RAM, 864KB SRAM, 4KB Backup SRAM.

• Clock and Power: 25MHz high-speed crystal oscillator; 32.768K 6pF low-speed crystal oscillator; 3.3V - 5.5V power input, with a maximum current of 1A for the internal 3.3V regulated output when 5V is input; uses USB C interface, with a diode in series to prevent power backflow.

• Interfaces and Buttons: 2×22 Pin 2.54mm pitch I/O interfaces ×2; 4 Pin 2.54mm pitch SW debug interface ×1; USB Type-C interface ×1; MicroSD card slot ×1; 8Bit DCMI interface ×1; user button K1(PC13) ×1; reset button NRST ×1; BOOT0 button ×1; DCMI camera interface comes with 1.5V and 2.8V power, no external adapter board needed, supports OV7670, OV2640, OV5640 sensors, and reserves AF circuit, supporting auto-focus function.

• Design and Quality: Adopts immersion gold TG155 board, four-layer board design; uses lead-free soldering process; sets BOOT in the form of a button; uses high-quality crystal oscillator with metal casing, all can oscillate well; always uses original ST chips; Github/Gitee regularly updates the batch number of chips used to ensure you purchase new chips; no factory test program is provided to prevent piracy and quality issues.

• Usage Notes:
  • How to enter ISP (Serial Download, USB Download):

    • Method 1: Press BOOT0 and NRST simultaneously, release NRST, release BOOT0 after 0.5S to enter ISP mode.

    • Method 2: In power-off state, hold BOOT0, power on, wait for 0.5S, release to enter ISP mode.

  • Development Methods and Examples: ST HAL Library: provides examples for GPIO, MSC, UVC camera, TFT, etc.; QSPI download algorithm: Keil, STM32CubeProgrammer.
