Great value but needs careful handling

The board performs well and has all the peripherals I need. Just be careful with the voltage levels on the GPIO pins; a multimeter check is advised before connecting sensors.

Excellent compatibility with CubeIDE

Set up was a breeze using STM32CubeIDE. The clock configuration tool made it easy to get the 72MHz speed running. No issues with the bootloader or flashing firmware.

5 FAQ

Q: Is the 5V pin tolerant on all GPIO ports?

A: Most GPIO pins on the STM32F103ZET6 are 5V tolerant, but please refer to the specific datasheet section 'Pin definitions' to verify which pins support 5V input, as some analog-only pins do not.

Q: Does this board come with an onboard programmer?

A: No, this board does not have an onboard programmer. You will need an external ST-Link V2 or J-Link debugger to flash code onto the microcontroller.

Q: Can I power this board via the USB port?

A: Yes, the board can be powered via the mini-USB connector, which provides 5V to the onboard regulator. Alternatively, you can supply 5V directly to the 5V pin header.

Q: What IDEs are compatible with this development board?

A: This board is compatible with STM32CubeIDE, Keil MDK, IAR Embedded Workbench, and platformIO. It supports standard C/C++ development environments for ARM Cortex-M3.

Q: Does it support FreeRTOS out of the box?

A: Yes, the STM32F103ZET6 has sufficient RAM and Flash to run FreeRTOS. You can easily integrate it using the STM32CubeMX tool to generate the necessary initialization code.
