GoKawiilFable 5 AI autonomously designs a working RPi Pico 2350 e-ink PCB from a text prompt
A hobbyist asked the Fable 5 AI tool to design a printed circuit board pairing a Raspberry Pi Pico 2350 with a GDEY0154D67-FL04 e-ink display, four buttons, and exposed I2C and GPIO pins, using only a single plain-English prompt. Unlike an earlier attempt with Claude Opus 4.8 that botched component orientation and routing, Fable 5 worked unsupervised for a few hours and produced a completed 31.8 x 37.32mm four-layer schematic and layout via KiCad's MCP integration, with no manual edits or checks from the designer before manufacturing.
GoKawiil's interpretation of the reporting above, not reported fact.
This experiment tests whether AI tools can move beyond code generation into physical hardware design, a domain requiring spatial reasoning, electrical correctness, and manufacturability that has historically resisted automation. If tools like Fable 5 can reliably generate manufacturable PCBs from natural-language descriptions, it could dramatically lower the barrier for hobbyists and startups to prototype custom electronics without specialized CAD expertise.
- The designer used Fable 5 to autonomously generate a full PCB design from a single natural-language prompt, with zero manual edits.
- The board integrates a Raspberry Pi Pico 2350, an e-ink display, four buttons, and I2C/GPIO breakouts on a 31.8 x 37.32mm four-layer board.
- A prior attempt using Claude Opus 4.8 for the same task failed due to poor component orientation and routing, highlighting notable variance in AI hardware-design capability.
