Visual wiring editor for FPV drones. Connect FC, ESC, motors, VTX, receiver and battery on a React Flow canvas. We validate in real time that each pin matches, voltages are correct and you're not shorting something critical. Useful before soldering.
Open circuit editor Back to configuratorThe big leap from "parts on the desk" to "all soldered and flying" is wiring. How many wires go from ESC to FC, which receiver pin maps to the right UART, where does +5V from the VTX go, which BEC powers what. The lab shows you visually and warns if a required connection is missing (motor without signal, VTX without GND, receiver without RX/TX).
The canvas is divided into 4 zones: power (battery + PDB + ESC), drive (motors), video (VTX + camera), radio (receiver + antennas). Each zone has its own rules. Put a motor in the video zone and we flag it. Connect a 5V VTX to a 12V BEC and error. Directional handles (← input / → output) help you not mix up pins.
When the diagram is done, open the "Find parts" panel and FPVBuilder suggests real catalog products matching your nodes' specs. If you drew a 2207 1900KV motor with XT60 6S, you get the real motors with those specs and cross-store prices.
