Other key parts include the switchsocket. By type, the board carries 4 connectors, 1 IC and 1 diode.

It belongs with the keyboards designs in this gallery.

From the project

Simple single switch 3/5 pin with hotswap compatibility for mechanical keyboard prototyping.

A simple single switch pcb for mechanical keyboard prototyping row and column matrices. PCB features a hot swappable socket and uses a 1n4148 SMD diode.

13 Feb 2022 - did the initial BOM. Created kicad project. Finished with hotswap socket symbol and footprint. To start on schematic.

14 Feb 2022 - finished schematic and pcb. Generated gerber file. Test print and check compatibility with hotswap socket and 3/5 pin switch.
