Claude Just Built a Custom PCB from Scratch—And It Actually Works

The process started with a single prompt directed at Claude Fable 5, which had been granted direct access to KiCad via the MCP protocol. The AI handled everything from the initial schematic layout to component placement and trace routing without a single manual edit from the human creator.

After a few hours, the design was ready, though it wasn't perfect. The model initially selected a couple of incompatible components, including a flash memory chip and a transistor that didn't fit the power requirements for the E-ink display. After a brief back-and-forth dialogue—where the AI iterated on its mistakes rather than the user fixing the files—the design was finalized and sent to JLCPCB.

The total cost for the AI-designed boards hit $150, plus a staggering $450 in Anthropic credits. Once the hardware arrived, the Raspberry Pi Pico 2 was programmed using Claude Opus 5 to handle an E-ink interface featuring a photo album, e-reader, and stopwatch. The board fired up on the first try, proving that a silicon brain can now navigate the complexities of electrical engineering better than most hobbyists.

This marks the point where the distinction between a 'creator' and a 'prompt manager' evaporates into thin air. While engineers spend decades mastering layout best practices, an AI can now churn out functional hardware by trial and error, leaving the human to simply foot the bill for the credits and the fabrication. It is an impressive shortcut, but it leaves one wondering if the craft of hardware design is being replaced by the art of babysitting a chatbot.
