3. What package does the STM32F103ZET6 use?
The MCU uses an LQFP144 package. Core boards typically use 2.0mm pitch pin headers to expose all I/Os in a compact form factor suitable for embedded systems; development boards feature richer interface layouts for peripheral expansion.

4. What applications is the STM32F103ZET6 Development Board / Core Board suitable for?
It is widely used in industrial control, medical devices, Human-Machine Interfaces (HMI) , IoT nodes, motor drives, data acquisition and signal processing, and embedded system learning. The STM32F103ZET6 is the highest-end configuration in the STM32F1 series, particularly suited for complex applications requiring large storage and rich peripherals.

5. What development tools support the STM32F103ZET6 Development Board / Core Board?
Recommended tools include Keil MDK-ARM (with STM32F1 Device Family Pack installed) and STM32CubeIDE. STM32CubeMX can be used for peripheral initialization code generation and clock tree configuration. Open-source solutions like VSCode + PlatformIO are also well-supported.

6. What is the operating temperature range of the STM32F103ZET6 Development Board / Core Board?
The chip's operating temperature range is -40°C to +85°C (ambient temperature).

7. What debug and programming interfaces does the STM32F103ZET6 support?
It supports both JTAG and SWD (Serial Wire Debug) interfaces. Some development boards also feature a one-click download function, allowing program programming via a single USB cable without the need to frequently adjust BOOT jumpers.

• Communication: 5×USART, 3×SPI, 2×I2C, 2×I2S, 1×CAN, 1×USB

• Memory Expansion: 1×FSMC (supports NOR/NAND/SRAM expansion)

• Memory Card: 1×SDIO

• Analog: 3×12-bit ADC (21 channels), 2×12-bit DAC

• Timers: 2 basic timers, 4 general-purpose timers, 2 advanced timers

• DMA: 2 DMA controllers with 12 channels total

9. What is the difference between STM32F103ZET6 and STM32F103VET6?
In the naming convention, Z indicates 144 pins and E indicates 512KB Flash. The STM32F103VET6 uses an LQFP100 package (100 pins), while the STM32F103ZET6 uses an LQFP144 package (144 pins) with more I/Os (112) and stronger peripheral expansion capabilities. The STM32F103ZET6 is positioned for high-performance applications, suitable for complex systems such as industrial control and medical devices.

10. What power supply options does the STM32F103ZET6 Development Board / Core Board support?
Multiple power supply options are supported: USB power (via Micro USB/Type-C interface), 5V DC input (via power jack or 5Vin pin), and JTAG/SWD debugger power. An on-board AMS1117-3.3 LDO regulator converts input voltage to 3.3V for the MCU. Some development boards also feature a VBAT backup battery holder (supporting CR1220 coin cell batteries) for RTC clock retention.
