ErgoBlue 2 Part List

General Notes

• All the quantity on this page includes parts for both halves.
• I recommend purchasing a couple of extras especially for the smaller/cheaper components in case if you make a mistake.
• Parts may be listed multiple times under different categories. You must buy enough for each category.
• This does not include obvious tools that you'll need such as a screwdriver, a soldering iron, a multimeter, and maybe some other stuff.
• You will absolutely need a multimeter to test as you build.
