Breadpad is a digital electronics breadboard exclusively for iPad, iPhone, Mac and Vision Pro. Place components, connect them, and simulate the result with a virtual oscilloscope.

Whether you are a student, hobbyist, or professional engineer, Breadpad can help you ideate, plan, and implement new circuit designs. Learn new concepts, tinker with prototypes, and evaluate changes to production systems.

Breadpad is free to get started.
