About the MiniRectangleDB PCB

MiniRectangleDB is an open source PCB design by GRAMCTRL, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 30 × 24.7 mm, with 10 components from 8 distinct parts.

Other key parts include the USBLC6-2SC6. By type, the board carries 3 resistors, 2 ICs, 2 connectors, 1 fuse, 1 diode and 1 capacitor.

It belongs with the keyboards designs in this gallery.

From the project

A modular and scalable design based on WunWae's Prism Controller

If you would like to support the developers of this project, consider purchasing parts like buttons, PCBs, USB-C to GCC cables, and official GRAM builds at GRAMCTRL.COM rather than a fab house.

Included Files - Included in this repo is all the files needed to get started with a PRI$M build: - PRI$M Frame .stl files - Aluminum Panel Gerber files (5 of 'em!) - PCB Gerbers for multiple hand layouts and a panelized version for the standard layout
