Unknown USB Device
I really like your project and can't wait to make one myself. I directly used UART to flash your bin file. I also installed the driver from Arduino_STM32. However, the Device Manager still shows an "Unknown USB Device". Is there a way to fix this, or do I have to use the ino file?
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.

Thank you for your reply. I think I’ll just follow your steps carefully. There’s one more question: in the BOM table generated from your .brd file, the 1µF and 2.2µF components are listed with a 0805 package, but the BOM table you provided specifies 0603. I’ve checked and the pads seem suitable for both 0805 and 0603 packages. Could you please advise which one I should follow?
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.

I'm very happy to say that I've successfully lit up the keyboard and it's now working properly. Since this keyboard comes with a built-in screen, I've been thinking we should make the most of this feature. Is it possible to use "Keybon Companion" to display the computer's status on the keyboard—like real-time CPU usage, memory, temperature, and more? Alternatively, could it show stock prices or weather? If it had these functions, it would definitely be very popular.
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 I am afraid you would have to implement this yourself ;)
