// one editor, four kinds of board

Protoboard Editor

Plan a circuit on the board you will really solder: stripboard, dot board, tripad board or a breadboard-style PCB. Draw the schematic once. Then place the parts by hand, with every net in its own colour, or let auto-layout place them and lay the cuts or solder runs for you.

Short guide

Browser-only version. Your projects stay in this browser on this device. Use Export in the editor to keep a backup file. Self-host the editor for accounts, share links and a parts library.

This fork is young and still grows. New board features land often.

start on a board

Each card opens a new project on that board. You can change the kind later in the editor.

Protoboard Editor with the schematic of a 555 LED flasher on the left and its dot board layout on the right — 555 LED flasher: auto-layout put it on a 7 × 18 dot board. each colour is one net, joined by solder runs.

from idea to board

1
Draw
Build the schematic from the symbol library or your own parts. The wires make the nets.
2
Choose the board
Pick the kind of board on your bench and its size. Presets cover the common perfboard sizes.
3
Lay it out
Drag the parts onto the board. Every net gets its own colour, and a short or an open connection shows at once.
or auto-layout
On stripboard and dot board the router places every part and lays the cuts or solder runs. How it works →
4
Print and solder
Print the 1:1 sheets, push the parts through the paper, then follow the cut or run sheet.
or go to PCB
When the prototype works, export a KiCad netlist and draw the real PCB.

what you get

Design

Schematic editor with a standard symbol library and automatic net detection
IC pinouts from the KiCad symbol library, plus your own custom parts
Parts drawn as real packages at true size: choose the body you have
Editable footprints and flexible leads for passives

Lay out

Four board kinds: stripboard, dot board, tripad board, breadboard PCB
Auto-layout for stripboard and dot board: placement, board size, cuts and runs
Lock the board size or single parts, and the router works around them
Off-board parts such as pots and jacks get pads or a connector

Build and share

1:1 print: placement sheet, mirrored cut or run sheet, parts list
KiCad-compatible netlist export
JSON export and import, full undo history
Edit and view-only links when you host it yourself

print and build

Printable 1:1 dot board build template: placement sheet, mirrored solder-run sheet and parts list

placement sheet on top, the solder-run sheet mirrored for the copper side, then the parts list.
