Bill of materials

Essentials:

Item	Count	Note
Keyboard PCB	2
Nice!Nano	2
12 pin headers and sockets	4	You can use through-hole diode legs as pins. Sockets spacing: 2.54mm, Socket height: Using minimal height sockets might not leave enough room to mount the battery under the MCU. 3DS1002-01-1*20V13-JK by CONNFLY are a good choice, but you can also use lower ones and longer legs instead. Spiltkb has a good guide on mounting.
LiPo battery (301230)	2	110mAh
Kailh Choc v1 switches (PG1350)	56
Keycaps	56
Kailh Choc hotswap sockets	56
Encoder EVQWGD001	2
Diodes 1N4148W	58	for each key + encoder
Buttons	2	reset buttons; 2 pins through-hole, tactile, 3x6x4.3mm
Slider Switches	2	on/off switches; SMD, C128955
USB-C Cable	1	for copying the firmware

Optional:

Item	Count	Note
Nice!View + mounts	2
Switchplate	2	Height: 1.2mm; either 3d printed or cut pcbs. stl
Case (Left + Right)	1	see here.
Silicone feet	8

Standing on the shoulders of giants

A great tutorial I referenced a lot by FlatFootFox: https://flatfootfox.com/ergogen-introduction/
Lots of inspiration and ideas for this project came from these boards: Choccy, Sofle, brain, spleeb
