OpenBaud connects Codex to local serial devices through an MCP server and plugin, with every write audited. It identifies ports from USB metadata, checks framing and checksums, and asks for acknowledgment before dangerous commands. Each byte goes to a capture that replays without hardware. The demo GIF and 46-second video show it on an ESP32-S3.

Nod answers Claude Code permission prompts from a 3-key pad built on a Seeed XIAO ESP32-S3: No, Always and Yes. The keys send the desktop app's shortcuts or, after a two-key hold, the terminal's numbered options. It works over USB-C or Bluetooth. The author says the Clawd-shaped variant was tested on hardware; the README shows renders, not photos.

rttsh is a Windows command-line terminal over SEGGER J-Link RTT for checking firmware on the board. Firmware exposes a command console through RTT, and Lua scripts on the host send commands and assert on replies and timing. It shares the flashing probe, leaves the UART free and includes an 8-tool MCP server. The README's 23 example scripts target an STM32H743.

Anup Ray reverse-engineered a Nokia 110 4G's firmware with OpenAI Codex and rewrote its Calculator app as an agent chat app. It sends messages to DeepSeek over the phone's SIM data and can check the battery, toggle the torch, place calls and set alarms. It loads into RAM from a computer, so a restart removes it.

Andreas Spiess's 18-minute video shows Claude Code taking ESP32 firmware from a written specification to passing tests on a Raspberry Pi testbench. The agent writes and builds the firmware, flashes it to boards on the bench, runs tests over Wi-Fi, MQTT, BLE and RF, and fixes failures until the tests pass. The skills and testbench code are open source.

GoFly says an AI agent designed a six-layer STM32F405 flight controller in EasyEDA Pro through easyeda-agent, then ordered it from JLCPCB with SMT assembly. The post says the agent then flashed the board over USB and ran basic function tests. The design keeps only the MCU, gyroscope and accelerometer, and testing stayed on the desk.

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.

Tony Huang built OpenMicroKbd, an open recreation of OpenAI's Codex Micro macropad on an STM32F072, whose schematic an AI agent wrote in CoHDL. Quilter.ai did the layout, an agent helped with the Rust firmware, and Huang had the boards fabbed and finished the assembly by hand. The launch post has photos of the assembled board and printed case.

In September Nordic Semiconductor added skills to its Nordic MCP server that drive a Power Profiler Kit II and SEGGER J-Link probes. The PPK2 skill captures long measurement runs and flags anomalies against a reference pattern; the debug skill runs GDB sessions. The nRF Connect extension for VS Code now shares build context. The post shows no runs.

Jorge García-Carrasco and colleagues published a benchmark in the Journal of Systems Architecture that scores LLM coding agents on 5 embedded-control tasks. Agents must build firmware, verify it and iterate under 4 feedback levels, from one-shot to oracle-style hints. The paper reports 420 runs on simulated ESP32 firmware: GPT-5.4 passed most often, and Qwen3.5-27B was the strongest local model.

Silicon Labs opened a public beta of its Simplicity AI SDK on 22 September, connecting AI coding assistants to its SDKs, tools and hardware. RFID Journal reports that GitHub Copilot and Codex are validated and that support starts with Bluetooth LE. A Hardware Intent Agent that drafts projects from board schematics is due in alpha in January 2027.

Iluvatar Labs had its research agent, Marvin, route AgentPad13, a two-layer RP2040 macropad modeled on OpenAI's Codex Micro. Marvin reached zero unrouted connections and zero DRC errors; FreeRouting and Quilter had left 18 and 19 unrouted. It also built and simulated the QMK firmware. Photos show the lit prototype.

Ori Grossman built a tilt maze game on a PIC24FJ256GA705 Curiosity board with Claude Code agents, an ADXL345 accelerometer and a 96x96 OLED. One agent drove the board's debugger through MPLAB's mdb command line and traced an I2C driver bug that dropped queued bytes. The README has a photo of the game running.

Adsum Networks' IoT Coder agent debugged a Fanstel BWG840 gateway whose nRF52840 BLE scanner ran cleanly but received nothing. It flashed an nRF52840 dongle as a Bluetooth sniffer and compared the air with RTT logs: 36 advertisements captured, none received. The cause was an RF front-end that was never enabled. This is a vendor demo of its own product.

Jacob Beningo gave Claude Code his Zephyr skills and a serial-port MCP server, then had it debug a sensor application on an NXP FRDM-MCXA156. The agent first blamed the hardware, and Beningo found the Click board mounted backward. Claude then traced readings of -45 C and 0% humidity to a conversion-timing bug. A screenshot shows its 83-sample check.

A DeepSeek Harness agent decoded the private UART link between a LinShang LS125 UV meter and its UVALED-X3 probe from measurements on the hardware. The probe answers a poll every 500 ms at 9600 8N1 with 28-byte frames checked by CRC-16/MODBUS. The README reports an STM32F103 host reading 21 of 21 frames with no CRC errors.

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.

Cliff Lasser built a clock from 128 Soviet IV-25 VFD tubes on eight boards, each run by an Arduino Nano ESP32 over RS485. He wrote about 15 pages of specification, and Claude wrote all the code, now over 8,000 lines. The first version, about 3,500 lines, ran on the first try with one bug: the display was rotated 180 degrees.

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.

Zhihan Zhang and colleagues, mostly at the University of Washington, published Embedded Arena, a benchmark that scores agents' model and firmware edits on microcontrollers. Boards include a MAX78000, an ESP32-S3 and an STM32N6. The paper reports Claude Opus 4.7 and Gemini 3.1 Pro failing every deployment without hardware feedback; with it, the first success came within 3 iterations.
