Vibe-design a PCB from a plain-English description
Describe the circuit you want. Banana Board generates validated firmware and wiring, then places and routes a real 2-layer board and exports fab-ready Gerbers. The preview below is not a mockup: it is an actual board routed by the same engine, graded and design-rule-checked live.
A real board derived at page-build time from a night-light circuit: placed, routed on two layers, and graded. Every chip (grade, DRC, copper length, vias) is a number the engine computed, not a claim.
From sentence to fab-ready board
Describe it
Write what you want in plain English. Banana Board generates the firmware, a wiring diagram, and a pin-by-pin map validated against your board's real pins.
It routes a real board
The engine clusters functional groups, places the parts, and routes copper on two layers. No manual dragging of traces, and no guessed connections.
It checks the copper
Every board is design-rule-checked and graded against the netlist. The numbers you see are derived from the actual routed copper, not marketing.
You export and order
Download fab-ready Gerbers and drill files for JLCPCB, PCBWay, or OSH Park, or export to KiCad to keep refining the layout.
Why the layout is trustworthy, not a guess
Most AI tools can draw a schematic that looks right. Banana Board validates every connection against the target board's real pin map, runs electrical-rule checks (power, ground, double-drive, input-only and strapping pins, ADC), then routes and design-rule-checks the copper. The board you export is the board that was verified, which is why the preview above can show its real grade and DRC pass count.
Vibe-design your PCB
Describe the board in plain English. Banana Board places the parts, routes the copper on two layers, checks it against the netlist, and hands you fab-ready Gerbers.
AI PCB design, answered
Can AI really design a PCB?
Yes, within limits. Banana Board turns a plain-English description into a placed and routed 2-layer PCB for its supported Arduino, ESP32, and RP2040 boards, then design-rule-checks the copper. It is built for common maker and prototype boards, not complex multi-layer professional designs, and every connection is validated against the board's real pin map so it does not invent wiring.
How do I generate a PCB from a circuit description?
Open the Studio, describe your circuit in one or two sentences (for example, 'an ESP32 that reads a BME280 over I2C and drives a relay'), and Banana Board generates the firmware, wiring, and a routed board. You can then refine it by chatting ('move the LED to another pin', 'make it easier to hand solder') and export the Gerbers.
Is the generated PCB actually manufacturable?
Yes. The board is routed on two copper layers, checked against fab design rules, and exported as standard RS-274X Gerbers with an Excellon drill file, mask and silkscreen layers, and a bill of materials, which is what board houses like JLCPCB and PCBWay expect.
What file formats can I export?
Fab-ready Gerbers and Excellon drill files, plus a KiCad export if you want to continue the layout in a full EDA tool. A bill of materials with distributor links is generated alongside the board.
How much does it cost?
There is a free tier, so you can describe a circuit and generate a validated board without paying. You only pay a board house when you decide to manufacture.
Which boards does the PCB designer support?
Arduino Uno, Nano, Mega, and Leonardo; ESP32 DevKit, C3, and S3; ESP8266 NodeMCU; and the Raspberry Pi Pico, Pico W, and Nano RP2040 Connect, with every design validated against that board's verified pin map.
Build it, do not just look it up
Describe your circuit in one sentence and Banana Board wires it to these exact pins, validates it, and lays out a fab-ready PCB.
