## Hardware Specifics
-This keyboard uses an integrated STM32G0B1 microcontroller fit with a single push button switch^[1](#references)^, and USB-C. It also features a dedicated IS31FL3733 RGB Matrix driver to alleviate processing power from the primary MCU for LCD drawing, or other tasks.

## Ordering
The following instructions will be for [JLCPCB](jlcpcb.com), but should generally apply to most PCB manufacturers. The Gerber files in this repository include:
- [**pcb_gerbers.zip**](production/pcb_gerbers.zip): Main PCB
-- [**plate_gerbers.zip**](production/plate_gerbers.zip): Switch Plate PCB^*^
+- [**plate_gerbers.zip**](production/plate_gerbers.zip): Switch Plate PCB<sup>*</sup>
- [**back_gerbers.zip**](production/back_gerbers.zip): Backplate PCB
* The switch plate PCB is designed for a single half of the keyboard (and is reversible), meaning ordering a quantity of 10 will be enough to cover 5 keyboards.
-3. For PCB assembly, choose **Economic** PCBA type and **Bottom Side** for assembly side
-4. Upload BOM file from [production/bom.csv](production/bom.csv) on the Bill of Materials page
-5. Upload CPL file from [production/positions.csv](production/positions.csv) as well. Disregard any message like "J1 won't be assembled due to missing data". This is the display pin header
-- Choose "File Provided as Complete File, proceed with my own files"
-6. Select appropriate components on the following screen by typing in
-the shown part number and select it. An effort has been made to choose
-as few extended components as possible, however this is not possible
-for some.
-7. Have a quick look at component placement and make sure nothing
-looks wildly wrong. It is normal for some components to be shown
-oriented incorrectly or not quite where they belong. The PCB reviewers
-will generally correct this without issue.
