  • The Return of the Square Inch Project

This project was created on 05/18/2017 and last updated 4 years ago.

Description

This project is to create a small breadboard friendly 1-bit full adder. These can be chained together to create a 4-bit or 8-bit adder, as well as combined with other logic such as "Dave's Boolean Bits" to create a simple arithmetic-logic unit (ALU). The PCB is 0.9" x 1.0" for a total of 0.9 square inches.
