Hi, you should be able to use any micro servo, but you have to check the exact dimensions. The 3D-printed parts and especially the screw holes will probably not fit...

@KlausMu I have not looked into it in detail, but a GitHub organization seems like a good fit for open source projects like this. We could also split the project...

Hi, honestly I always went and installed the bootlader first and then uploaded the Arduino sketch. Maybe flashing the bin file alone is not enough.

I have only used 0603 parts myself but you could use both 0603 or 0805 in that case. The different pads might be a mistake from copying Sparkfun's library parts.

Great to hear that you got your Keybon to work! The features you describe are definitely possible with this hardware. You could probably even display videos on the screens. But...

Hi, are you using the right core for the STM32? That should be https://github.com/rogerclarkmelbourne/Arduino_STM32 which includes a USBComposite.h. And for the button library, I found this folder in my Arduino...

I can try to compile it on the weekend. It's been a while since I programmed the STM32. The folder structure should be Documents/Arduino/hardware/Arduino_STM32/drivers, tools, etc... And are you sure...

Great, I'm glad that you got it to compile! And flashing the bootloader can be tricky, too. About the key functions: I just plugged in my keybon and ran the...

I don't see why the bluepill should work differently from the keybon board. Have you tried the compiled exe from GitHub?

Sorry, I missed your edit. Interesting find, maybe I never noticed this because my PC usually has an unused COM1. COM14 is the default port (portName) that I must have...
