Logic Gates Board with LED indicators and labeled switches

Overview

Bring abstract truth tables to life. This matte-black PCB gives students tactile switches, bright yellow LEDs, and printed logic symbols so they can see how AND, OR, NOT, NAND, NOR, XOR, and XNOR gates actually behave.

It ships fully assembled. Add power, flip a switch, and the board animates to confirm everything is live.

Perfect for: first-year computer science courses, makerspaces, electronics clubs, and hands-on workshops.

Key features

Truth table and logic symbology silk-screened next to each gate
High-brightness 3 mm amber LEDs (λ ≈ 590 nm) for instant feedback
Satisfying toggle switches so students feel each state change
Animated power-on sequence that checks every LED and gate
Complete boolean operator set with independent outputs
