Recent updates allow simulation frequencies up to 96,000 Hz, enabling the creation of working 8-bit CPUs. Platform & Requirements

CRUMB is available as a paid app on several platforms, including Steam ($8.99), the App Store , and Google Play . OS: Windows 8 (64-bit) or MacOS 2015+. Processor: Intel Core i3. Memory: 4 GB RAM. Storage: 1 GB available space. Prototyping Tips for Beginners

Switch to "Analysis" mode to see wire color changes that indicate voltage levels.

Place a 12V DC power supply or battery and connect it to the breadboard rails first.

Features a Code Editor to program microcontrollers directly within the simulator.

Includes passives (resistors, capacitors), semiconductors (BJT, MOSFET), logic gates, EEPROM, and displays.

CRUMB Circuit Simulator is a real-time 3D electronics simulator designed for interactive learning and prototyping on a virtual breadboard. It allows users to build complex circuits using a wide range of components—from basic resistors and LEDs to programmable microcontrollers like the Arduino Nano—without the risk of hardware damage.

Build circuits in a realistic 3D workspace that mimics a physical workbench.
