You can read more about the tools you can use in the following article: What tools do I need to assemble a keyboard kit?
With the parts and the tools out of the way, we can now start with the build!
Both PCBs are the same: they’re reversible. Choose one half as the left, and the other as the right. The bottom side of each PCB will get the diodes and RGB LEDs. The top side of each PCB will get the remaining components.
You’ll need to repeat all of the assembly steps of this guide for both halves: once for the left half, and once for the right half. Be mindful, as undoing some build steps can take a lot of effort.
