HeyPCB's MCP server connects Claude Code, Codex or Cursor to its hosted KiCad board-design service. An agent can ask HeyPCB to build the whole board with build_board, or add parts and connections itself and call check_board until each finding is fixed. A local npm package adds KiCad project upload and Gerber export. The vendor README shows no fabricated board.

Munetomo Maruyama had Claude Code design mmRISC-2, a 64-bit RV64GC RISC-V core, and brought it up on a Digilent Arty A7-100T. Claude wrote the specification, SystemVerilog RTL, testbenches and documents; Maruyama ran Vivado and the board. Bring-up logs in the repository record Linux 7.2 booting to a shell at 50 MHz and a 120-minute stress test passing.

Tide & Wind Tracker shows tides and wind on an M5Stack PaperColor and tests its e-paper rendering on the ESP32-S3 itself. Test firmware renders fixtures sent over USB and returns the canvas bytes for comparison with golden images. Claude Code iterated against those tests while a person approved every change. The README has a photo of it running.

Artificial Analysis launched AA-Robotics v0.1, a benchmark in which language models in coding-agent harnesses control a Hiwonder NexArm robot arm. Models in Codex, Claude Code and Antigravity write code for 8 zero-shot tabletop tasks, watching through 4 cameras. GPT-6 Astra led with 69.4 and Claude Opus 5.5 scored 48.8. Models took about 30 minutes a task; people averaged 20 seconds.

JLCPCB's guide shows Claude Code designing a 5 A XL4015 buck converter in KiCad 10 through the kicad-mcp-pro server. Claude built a 16-net schematic and routed a 63 by 33 mm board with an A* router it wrote in Python. A netlist check caught an ISENSE to ISET short that ERC only warned about. The guide says nothing was fabricated.

Andrew de Quincey had Claude Code port the Frank Micro BBC Micro emulator to the RP2350-based Adafruit Fruit Jam. Claude studied the codebase, planned around clock and PIO conflicts and wrote a script for the audio codec registers. Photos show the emulator booted over HDMI. It ran Exile, and an odd Mac keyboard was the only snag.

A JLCPCB blog author had Claude Code with Opus 5.5 rebuild a CH32V006 component tester in EasyEDA Pro from a PDF schematic. Working through a local API bridge, Claude swapped 8 out-of-stock parts, placed 47 parts and routed the 2-layer board with Freerouting to zero DRC errors. The post says the board was not fabricated or visually reviewed.

Tiny Engineer is an open-source desk robot that acts out a coding agent's work. It looks around while files are read, types while code is written and rings a bell when the task ends. An ESP32-C3 on an open KiCad control board drives five SG90 servos and an OLED face. The README links a demo video and build photos.

In an Octopart video, one prompt sends Claude Code through a digital low-pass filter on a Digilent Cmod S7 FPGA board. It writes and simulates the filter, then programs the board over JTAG. Through MCP servers for an Analog Discovery 2 and a Rigol scope, it sweeps test tones at 1, 5 and 15 kHz against the 10 kHz cutoff.

In a dev.to post, an embedded developer lists board facts that broke LLM-written firmware after it compiled and flashed. An ST7789 panel needed a 34-pixel offset. A Waveshare ESP32-C6 board shares SPI lines between its display and SD card, and ESP32 ADC2 stops working while Wi-Fi is on. The author's answer is mcu-skills, Claude Code skills for 8 boards.
