• Operating Voltage: 1.7V ~ 3.6V

• Temperature: -40°C ~ 85°C (industrial grade)

• ADC: 1×12-bit, 10 channels

4. What package do both chips use?
Both chips use the UFQFPN-48 package (7mm × 7mm) with 0.5mm pin pitch. Core boards typically expose all I/Os via 2.54mm pitch pin headers.

5. What is the difference between STM32F411CEU6 and STM32F401CCU6?
Both share the same Cortex-M4 core, package (UFQFPN-48), and 36 I/Os. Key differences are:

6. What applications are these core boards suitable for?
They are suitable for embedded system development, IoT, robotics, motor control, industrial automation, and medical devices. The F411 is better for data processing and complex algorithms due to higher frequency and larger memory; the F401 is a cost-effective entry-level choice.

7. What development tools support these core boards?
Recommended tools include STM32CubeMX (configuration) and STM32CubeIDE (IDE). Both chips have excellent MicroPython support with ready-to-use firmware. They also support Arduino IDE and C language development. The F411 supports DFU protocol for USB firmware updates.

8. What is the operating temperature range?
Both chips are industrial-grade with a temperature range of -40°C to +85°C. Some F411 versions offer a wide-temperature option from -40°C to 105°C.

9. What peripheral interfaces do these core boards support?
Both chips support rich peripheral interfaces:

• Communication: 3×I2C, 3×USART, 5×SPI (with I2S), 1×USB 2.0 OTG (full-speed with PHY)

• Storage: 1×SDIO (supports SD/MMC/eMMC)

• Debug: SWD and JTAG

• Timers: Up to 11 (including motor control PWM and 32-bit timers)

• ADC: 12-bit, 16 channels on F411, 10 channels on F401

10. What are common versions of the F411 core board?
Common versions include the DFRobot STM32F411 BlackPill and the WeAct STM32F411CEU6 (designed for MicroPython with USB-C). Some versions have SPI Flash pads for external storage expansion up to 16MB. The F401 core boards typically feature Micro-USB interfaces.
