This is an ARM-powered 65% keyboard PCB with USB Mini B connector and breakout for optional RGB underglow.
Keyboard Maintainer: Coarse
Hardware Supported: Vinta with STM32F042K6T6
Hardware Availability: Private Groupbuy
Make example for this keyboard (after setting up your build environment):
make coarse/vinta:default
See build environment setup then the make instructions for more information.
STM32F042xx chips does not allow jumping to bootloader without BOOT0 being set to high, therefore it is impossible to enter the bootloader from sending a QK_BOOT keycode nor using bootmagic or bootmagic lite.
The only way to enter bootloader is to hold the BOOT0 button while the keyboard is powering up or after a power reset (done by pressing the reset switch or sending a QK_BOOT keycode).
