* Starting point for blue pill based practice60

* Changes

* add

* try raw bin no botloader

* swap back to bootloader version

* edit

* Remove debug LED flash

* Disable JTAG to open up B3 and B4

* Add led backlight support (no breathing yet)

* Update matrix for correctness

* RGB Underglow working in a very simple state

* not as bright

* Move to handwired

* revert ChibiOS_Test changes

* Changes based on PR comments

* Address PR comments v2

* Move files
