PCBStudio - PCB Board Designer

Design, route, and print real PCBs on iPhone and iPad. Templates, autorouter, DRC, Gerber, and AirPrint mask export built in. AI-generated layouts from a single sentence.

PCBStudio puts a full-featured PCB design studio in your pocket. Whether you are a student building your first Arduino board or a professional engineer reviewing a layout on the go, PCBStudio gives you the tools to design, route, check, export, and now physically fabricate real printed circuit boards — entirely on iPhone or iPad. PRINT YOUR OWN PCBs AT HOME

Version 3.0 adds direct PCB mask export for DIY fabrication. Generate a true 1:1 scale black-on-white image of any copper layer and print it directly via AirPrint — no computer needed. Enable the mirror toggle for toner transfer, or leave it off for UV photoresist. FOUR MODES FOR EVERY SKILL LEVEL

Reference Library — Browse 25+ built-in components with full schematic symbols, footprint options, pin-level detail, and typical usage guidance. Covers resistors, capacitors, MOSFETs, NPN/PNP transistors, LEDs, ATmega328P, RP2040, ESP32-S3, STM32F103, op-amps, shift registers, USB-C, LDOs, and buck converters. Template Generator — Choose from 6 professional circuit templates: USB power supply, 3.3V LDO regulator, ATmega328P minimal design, RP2040 minimal design, H-bridge motor driver, and I2C sensor interface. Configure key parameters and generate a complete board layout in seconds. AI Design Assistant — An optional module that connects the AI provider of your choice to PCBStudio's design engine. Add your own API key for Claude (Anthropic), GPT-4o (OpenAI), or Gemini (Google) in Settings, then describe the circuit you need in plain English. The AI returns a complete PCB design — component selection, net connections, BOM, placement, and design notes — and the result opens directly in the CAD editor with one tap. No API key? The assistant still answers general PCB questions and design guidance using its built-in knowledge base. Full CAD Editor — A complete multi-layer PCB editor with component placement on F.Cu and B.Cu, trace routing, via insertion, and a Lee wave-propagation autorouter with A* heuristic, diagonal routing support, and automatic via insertion for layer transitions. Design Rule Check (DRC) catches trace width violations, clearance errors, short circuits, via size problems, overlapping components, and board boundary violations before you export. EXPORT TO INDUSTRY FORMATS

Export your finished board directly from the app:

— Gerber RS-274X — copper, silkscreen, solder mask, and drill files

— KiCad .kicad_pcb native format

— SVG and PDF for documentation and review

— JSON netlist for third-party tools

— ZIP archive with the complete Gerber set ready for fabrication

— 1:1 scale copper mask PDF/SVG for DIY toner transfer and UV photoresist BUILT FOR PROFESSIONALS AND BEGINNERS

Design rules are fully configurable per board. Choose from presets — Standard (0.25mm trace, 0.2mm clearance), Fine Pitch (0.1mm trace), or JLCPCB — or dial in your own values. The template generator makes it approachable for newcomers; the autorouter, DRC engine, and Gerber pipeline give professionals the precision they need. AI ASSISTANT — YOUR API KEY, YOUR CHOICE

The AI Design Assistant is an optional feature. PCBStudio does not bundle or bill for AI access — you bring your own API key from whichever provider you prefer: Claude (Anthropic), GPT-4o (OpenAI), or Gemini (Google). Enter your key once in Settings and it stays on your device. The AI returns structured PCB data — reference designators, net connections, board dimensions, BOM, and design notes — not just text. Generated boards open directly in the CAD editor for fine-tuning. Usage costs are billed directly by your chosen AI provider according to their standard rates. PROJECT MANAGEMENT

Save unlimited projects to your device. Each project stores the complete board state — components, traces, vias, nets, and design rules — in a portable file. Projects autosave automatically every 30 seconds so no work is ever lost.
