About the Gate or 2in PCB

Gate or 2in is an open source PCB design by tmarhguy, published on GitHub under the MIT license. It is a 2-layer board measuring 57.5 × 36 mm, with 6 components from 2 distinct parts.

From the project

8-bit combinational ALU built from scratch with 3,488 CMOS transistors (KiCad + SPICE + Logisim + 1.24M tests

This directory contains individual circuit modules organized by component type and specifications.

The modules are organized to match the component inventory requirements:

- adder1/ - Single-bit full adder - adder2/ - 2-bit full adder - adder8/ - 8-bit full adder

- alucore/` - ALU core module integration

1. Primary Modules: Use the organized subdirectories (e.g., gateand/gateand4in/`) for new designs matching the component inventory.
