CircuitToolsMT

CircuitToolsMT is an electronic circuit editor—for both schematics and PCBs—designed for designing, learning, and prototyping from your phone, tablet, or desktop.

Draw your circuit by placing components, connect them with wires, and switch to PCB view to route the traces. All with a fast touch interface and a full-screen canvas.

✨ MAIN FEATURES
• Over 230 components: resistors, capacitors, diodes, LEDs, transistors (BJTs and MOSFETs), regulators, ICs (555 timers, op-amps, logic), connectors, power supplies, and much more—in both THT and SMD versions.

• Dual view: SCHEMATIC and PCB, with instant switching.

• Nets and connection highlighting.

• DRC (Design Rule Check): detects unconnected pins and insufficient clearances, with navigation for each alert.

• Autorouter: routes a single connection and the ENTIRE board, including two layers of copper and vias.

• Multi-layer auto-router with auto-vias: Uses both sides and inserts vias automatically to avoid obstacles.

• Through-through vias and true physical footprints per package.

• Export your board to Gerber (8 layers: top/bottom copper, masks, thermal paste, silkscreen with text, outline, and holes) ready for fabrication.

• Export the schematic or PCB to PNG.

• Sample electronics drawings to load and start instantly.

• Light/Dark mode (or follow the system's color scheme).

• Available in 20 languages.

🔌 No annoying permissions: Save your projects to the app's private storage. No ads.

Ideal for electronics students, makers, hobbyists, and professionals who need to sketch or document a circuit anytime.
