Logic Trainer
A modular workstation for deep digital logic exploration
Available now · $79.99
Overview
Build and debug full digital systems without leaving the bench. The Logic Trainer combines a controllable clock, jumpers, memory, multiplexers, counters, and visualization so learners can experiment with sequential logic using real signals.
Configure combinational blocks, observe propagation through the RGB LED array, and store values in the onboard registers. Every module is labelled and wired for quick breadboard-style experiments.
Designed for: university labs, advanced high school programs, prototyping workshops, and self-taught builders who want more than a simulator.
