    Properties

    The system architecture features a USB-powered 3.3 V power tree: VBUS (5 V from USB) is routed through the VSYS regulator to produce a stable 3V3 rail. The MCU core runs at 3.3 V and serves as the primary system controller. An external SPI flash interface provides non-volatile storage connected directly to the MCU’s SPI pins. USB data lines and power input are protected by ESD diodes and reverse/over-voltage protection circuitry. A SWD debug header exposes SWDIO, SWCLK, RESET, 3.3 V, and GND for programming and debugging. A separate user I/O header routes key MCU GPIO, UART, SPI, and I²C signals for peripheral expansion.
