What is BBRouter?
BBRouter is a browser-based 3D breadboard editor and simulator designed for electronics hobbyists and educators. Users can place components like logic chips, LEDs, switches, and Arduinos onto virtual breadboards exactly as they would appear in a physical build. The platform simulates the resulting circuit, supporting 74LS, 74HC, CD4000 series logic, 555 timers, memory chips, and emulated Arduino sketches. A built-in oscilloscope view allows users to probe any connection point during simulation.
The tool validates user layouts against imported netlists from KiCad, EasyEDA, Digital, Logisim, and SPICE. It automatically routes missing wires, generates clean schematics in a KiCad-inspired style, and flags potential wiring mistakes before physical assembly. BBRouter exports practical documentation including step-by-step build instructions and CSV bills of materials. It runs on desktop and mobile browsers, requires a free account for full access, and offers a guest mode for quick testing. Advanced users on the Maker plan can connect external AI applications via an MCP server to inspect and modify projects.
