About the Motherboards PCB
Motherboards is an open source PCB design by wafer-space, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 16.5 × 90.2 mm, with 6 components from 3 distinct parts.
From the project
Wire bonded chip on board PCB designs.
We've designed several example breakout and motherboard PCBs to simplify development and integration with your custom chips.
We have also developed a set of KiCad symbols to support design and integration with our COB layouts. These symbols are included in the Motherboards examples and can be used as a reference for your own designs.
