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.
