It work very well. Programming is easy using stm32duino with PlatformIO. Flashing is easy using NRST and BOOT0 with a single finger to activate DFU over USB. Debugging is simple using serial port over USB. One important thing need to be noticed: if you can't see DFU firmware after doing the DFU boot sequence, warm-up the stm32 chip with your finger. It need to be at least at 25 degC to work. Even with this DFU issue, it stays a very good product.

Top! Pinders are included and programming via the SWD interface works fine. Although the USB-C interface is there, there is no USB bootloader written on the chip. Purely theoretically one would have to be able to program it also via USB-C, if a corresponding bootloader was written. For this one needs a programming device (ST-Link). In my case I use the St-Link interface of an old broken Nucleo development board.

Top! Pinnender sind mit dabei und Programmierung über die SWD Schnittstelle funktioniert einwandfrei. Die USB-C Schnittstelle ist zwar da, jedoch ist auf dem Chip kein USB-Bootloader geschrieben. Rein theoretisch müsste man ihn auch über USB-C programmieren können, wenn ein entsprechender Bootloader geschrieben wurde. Dazu braucht man ein Programmiergerät (ST-Link). In meinem Fall verwende ich die St-Link Schnittstelle eines alten kaputten Nucleo Entwicklungsboards.

Works well. I use the ST-link V2 programmer and the STlink-gui software to download the binary file generated by the STM32CubeIDE software.

Fonctionne bien. J'utilise le programmeur ST-link V2 et le logiciel STlink-gui pour télécharger le fichier binaire généré par le logiciel STM32CubeIDE.

Nice quality. USB-C is great. Ideal for all sorts of DIY projects. Mine will be used for a custom mechanical keyboard.

Board looks good and well built. Working fine from basic checks. 90 degree connectors were missing. Apart form that exactly as in description and image. Took over a month to deliver to India via India direct mail. Tracking information stops updating after dispatched and resumes only after the packet moves out of customs in India(after about a month in my case).
