Excellent STM32 entry point
Coming from Arduino, this was a smooth transition. The 84MHz clock speed handles complex logic easily. Documentation online is plentiful for this specific core.

Compact and powerful
Love how small this board is while still breaking out all the essential pins. Used it for a sensor data logger project and it ran for weeks without issues.

Solid build quality
PCB quality looks professional. The USB-C port is a nice touch for modern setups. Only minor issue was finding the right driver for my older Windows machine initially.

Perfect for MicroPython projects
This board works flawlessly with MicroPython. Flashing the firmware was straightforward, and the GPIO pins are clearly labeled. Great value for learning embedded systems.

Best value Cortex-M4 board
I bought five of these for a university lab. They are robust, easy to program via ST-Link, and the students picked up MicroPython on them very quickly.

Good performance, headers need soldering
The chip performance is excellent for the price point. Just be aware that you need to solder the pin headers yourself, which is fine for hobbyists but might annoy beginners.
Q: What is the difference between the RCT6 and CCU6 versions?
A: The main difference is the Flash memory size. The RCT6 has 256KB of Flash, while the CCU6 has 128KB. Both have 64KB of SRAM and run at 84MHz.
Q: Does this board come with the pin headers pre-soldered?
A: No, the board typically comes with unsoldered pin headers in the package to allow for flexible mounting options. You will need to solder them yourself.
Q: Does MicroPython come pre-installed?
A: Usually, the board ships with a basic demo or empty firmware. You will need to download the latest MicroPython .bin file for STM32F401 and flash it to the device.
Q: Is an external debugger included in the box?
A: No, the package only includes the core board and pin headers. You will need a separate ST-Link V2 or similar debugger/programmer to flash code if not using the bootloader via USB.
Q: Can I use the Arduino IDE with this STM32 board?
A: Yes, you can use the Arduino IDE by installing the STM32duino board package. It supports both the RCT6 and CCU6 variants.
