Why Circu?

Built for Breadboard-Style Circuits

Skip the learning curve of full EDA tools. If you can build it on a breadboard, you can turn it into a PCB with Circu.

Breadboard-Compatible Layout
Everything snaps to standard 2.54mm breadboard spacing. If it fits your breadboard, it fits your PCB in Circu.
Easy to learn
Utilize a modern Auto-Router. Go from breadboard prototype to order-ready PCB without learning KiCad.
Manufacturing-Ready Gerber Export
Export standard Gerber + drill files you can upload directly to JLCPCB or PCBWay.

Breadboard to PCB in 3 Steps

Recreate your breadboard layout, connect pins like jumper wires, and export a PCB you can manufacture.

1
Place Breadboard Parts

Pick breadboard-compatible parts from our library (Arduino/ESP32 boards, sensors, resistors, LEDs, buttons, headers, and more).

2
Connect Pins like Jumper Wires

Click pins to create connections. Circu uses those connections to generate clean PCB traces automatically.

3
Preview in 3D & Export Gerbers

Click Finalize PCB to preview your board in 3D and export manufacturing-ready Gerber files for JLCPCB or PCBWay.
