MetaphoricV2
About the MetaphoricV2 PCB
MetaphoricV2 is an open source PCB design by OldWer, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 204.5 × 138 mm, with 140 components from 65 distinct parts.
Other key parts include the HCS10017, 74F04, 74LS257, 4464 and 28C256. By type, the board carries 50 resistors, 32 capacitors, 19 ICs, 12 connectors, 12 diodes and 8 transformers.
From the project
An Oric clone
The repository contains two directories with KiCAD projects for the main PCB and the keyboard PCB. The bill of materials is available in BOM.* files in the respective directories (in .csv, .xlsx and .PDF formats). In the gerbers subdirectories there are gerber files ready for manufacturing (I used recommended JLCPCB settings when exporting the gerbers). In the main PCB's STL subdirectory there are 3D models for a simple case and also for a spacer which you can print in 5 copies and which is used to separate the two boards. In the keyboard's STL subdirectory there is a 3D model for a holder…
