CRUMB is a user-friendly and interactive program that provides an introduction to electronic circuits. Developed by Vital Group Limited, this program offers a fully realized 3D experience, allowing users to construct prototype circuits without the risk of component failure or the hassle of ordering individual components.

With a wide selection of components available, CRUMB enables users to dive straight into creating prototype circuits. From studying the workings of transistors and audio filtering to programming an EEPROM to run a basic program, this program caters to both beginners and enthusiasts.

CRUMB also features a built-in oscilloscope and analysis views, allowing users to clearly observe the interaction between components from within the wires themselves. This provides a valuable learning experience for beginners and a platform for analyzing and perfecting prototypes for enthusiasts.
