From the project

A Software Configurable Solderless Breadboard

The goal is to evaluate the educational benefits and potential drawbacks of these software-configured hardware systems compared to traditional manual wiring. By doing so, it addresses the need for balancing hands-on skills with error minimization and conceptual understanding in electrical engineering education. # Analog switch matrix cross point experiment breadboard. # Production PCB (Red3 version, instructions for ordering boards can be found in PCB Projects folder)
