It does seem MORE than a little bit strange that when you order both a SoloKey and a DiceKey set from Circuit Supply, you end up with a SoloKey that...

Annnddddd.... it looks like I can't reprogram my SoloKey. How do I get one that is pre-programmed with the 5.0.0 version? usb.core.USBError: [Errno 13] Access denied (insufficient permissions)

Annndddddd .... my SoloKey has disappeared, replaced by the STM32 BOOTLOADER, with a difference idProduct of df11, and I can't talk to it using solo anymore.

Anybody know how to get my SoloKey Tap USB-A out of dfu / bootloader mode? Yeah, I didn't read carefully and didn't see that the instructions were for a Solo...

Here's how I got it out of DFU mode: https://github.com/solokeys/solo/issues/601 I still can't reprogram it with the DiceKeys fork.

Right, but how do I program this firmware into my Solo?

Hall sensors work great. With the analog kind, you can adjust exactly where the trip point is.

The analog hall sensors require an A/D input for each key. Practically, you need to use an A/D multiplexor.

Sparkfun just pointed me to this product: https://www.sparkfun.com/products/23880 It's an analog hall effect sensor which is interfaced via I2C ! So you wouldn't need a boatload of analog multiplexors, just...

@Dracozny It's about the chip, not the board. You would of course put it onto a keyboard PCB.
