CRUMB
Great selection of components
CRUMB for Android is a comfortable application with interactive 3D modeling that will help you simply and efficiently create electronic circuits. A comfortable interface, simple controls and a large selection of components are prepared for you to help you prototype circuits in 3D, as well as avoid the hassle and failure of terminal components associated with individual parts. By downloading the application, you can immediately start creating prototypes of circuits, as a large selection of various components is prepared for you, an accessible catalog and the opportunity to gain also theoretical knowledge, studying the operation of transistors and sound filtering, up to Programming EEPROM.
You can download CRUMB for free on Android and use the application to create electronic circuits. CRUMB is easy to understand for beginners as it helps to lea the nuances of various components, while advanced users can analyze and refine prototypes before building real-world models. The application will please you with a built-in oscilloscope, and will also allow you to trace and evaluate all analytical representations, see the interaction between components within the wires themselves and gain new knowledge. Each new update will add even more different components and functions, theoretical materials and opportunities for creating unique electronic circuits to the application.





How to update CRUMB
