Excellent for MicroPython
Flashed MicroPython immediately. The board is tiny but packs a punch. Great for portable projects.

Solid STM32 option
Standard pinout makes it easy to integrate. Documentation online is sufficient for most tasks.

Perfect for workshops
Bought 10 for our club. All worked out of the box. Pin headers are well soldered.

Good value core board
Works well for learning embedded C. Wish it had an onboard debugger like Nucleo boards, but price is fair.
Q: Does this board come with pin headers soldered?
A: Most versions come with headers unsoldered for flexibility, but check the specific variant image.
Q: Is Arduino IDE supported?
A: Yes, you can install the STM32duino board package to program it using Arduino IDE.
Q: What debugger do you recommend?
A: We recommend the ST-Link V2 or V3 for debugging and flashing firmware.
Q: Does it support FreeRTOS?
A: Yes, the STM32F4 series is fully compatible with FreeRTOS and other RTOS solutions.
Q: Can I power this via USB?
A: This is a core board without USB interface. You need an ST-Link or USB-TTL adapter for power and programming.
