Claude Fable 5 designs an RP2350 e-ink board through a KiCad MCP server
A Reddit user had Claude Fable 5 design an RP2350 e-ink board through a KiCad MCP server, allowing no manual edits. Wccftech reports several rounds to fix wrong part picks. Five assembled boards cost 130 euros plus $450 in API credits, and Claude Opus 5 wrote the firmware. Photos show the board driving its 1.54-inch display.

Cardputer-Adv agent skill: four firmware traps from one hardware session
cardputer-adv-skill gives Claude Code or Codex the build and flash procedure for M5Stack Cardputer-Adv firmware with PlatformIO and M5Unified. Its README lists four traps: qio flash mode never boots, Serial.begin blocks without a host, opening the port resets the chip, and esptool 4.5.1 cannot sync. The author says every claim was measured on hardware.

SAIHub: an ESP32-C5 IO board that serves MCP so agents can drive real pins
SAIHub firmware runs on an ESP32-C5 and serves MCP over Wi-Fi to coding agents such as Cursor and Claude Code. Agents can drive eight GPIO pins, generate PWM up to 50 kHz, capture edges, use a UART, switch 3.3 V and 5 V rails and run Lua scripts on the board. The README shows no photos or test results.

ATK-Logic-MCP: an MCP server for the ALIENTEK USB logic analyzer
ATK-Logic-MCP connects MCP clients such as Claude Code to the ALIENTEK ATK-Logic-Analyzer, a 16-channel USB logic analyzer. It captures at up to 200 MHz, decodes buses with the 208 sigrok decoders from the vendor install and reads or writes vendor archives. The README says the USB protocol was reverse-engineered from vendor source and checked against the device.

rigol-mcp: an MCP server for Rigol oscilloscopes, tested on the DHO814
rigol-mcp connects any stdio MCP client to a Rigol oscilloscope over LAN and runs only in a container. Its tools set up channels, take measurements and save waveform captures and screenshots. The DHO814 is the main tested model, and the server labels each capability fact by how it was verified. The README lists smoke tests run without an input signal.

pcb-skill: an agent skill from hardware idea to a staged PCB order
pcb-skill takes Claude Code or Codex desktop from a hardware idea through schematic, sourcing and EasyEDA Pro layout to a staged PCB order. Each phase ends at a gate, and the agent stops at the pre-payment page. The README's case-study board, an ESP32-P4 music player, was staged for order but not fabricated or powered.

ws-pico2go: an agent-first MicroPython workspace for the Waveshare Pico2Go robot
ws-pico2go sets up Claude Code to program the RP2350-based Waveshare Pico2Go robot in MicroPython, entirely from the terminal. Waveshare publishes no pinout, so the author recovered one from a schematic PDF and keeps it in CLAUDE.md with safety rules and measured sensor behavior. The README says an obstacle avoider runs untethered. We have not seen video.

Embedder and SEGGER give a firmware agent direct control of J-Link probes
SEGGER and Embedder announced on 10 September that Embedder's firmware agent can now drive J-Link and J-Trace debug probes. The announcement says the agent loads builds, sets breakpoints, reads registers and memory and watches RTT output, then keeps debugging on the target until the code works. It gives no availability date or price.

Copperhead launches an agentic circuit-board design tool that compiles to KiCad
Copperhead launched on Hacker News as an agentic circuit-board design tool that compiles designs to KiCad files and manufacturing outputs. The founder writes that it works on its own hardware representation instead of editing KiCad directly. The thread drew 250 points. No board made with Copperhead was shown, and assembled-board ordering is still planned.
