32u4 based keyboard

[helpful]

Components are soldered. I have a QMK keyboard files and Keymap files.

How do I flash? if my fork has not been merged?

If you have source code, QMK's documentation should tell you what you need to install and run to compile. Compilation would result in at least a ".hex" file and a few others.
If you downloaded a ready-made firmware, you should have a .zip file (or whatever) that contains the .hex file.

There should be a USB-capable bootloader on the chip. There are multiple different ones for different boards.
You would have to find out which one is used by your board and get the appropriate loader program that would talk with the bootloader. Then start that program and follow the program's instruction to load the ".hex" file onto your board.

Thanks, I was doing all that and I figured I was missing a step.

Apparently I soldered all my MCU's the 180 degrees incorrectly.

Thanks. I need to lock this thread and delete it before I make more of a fool of myself
