Interface
Serial ports and UARTs, the console most boards print to, which agents read and write to flash, test and debug.
The most active tools first.

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.

ae-hw-bridge connects AI agents over MCP to a target board through HW Puppet, MicroPython firmware for an ESP32-S3-DevKitC-1. Over one USB cable, HW Puppet drives the target's reset, boot and power lines and bridges its UART console. A mirrored terminal shows a person the same log the agent reads. Neither README shows a recorded run.

K-Dense's LabMCP connects Claude and other assistants to lab instruments through 32 MCP servers. They cover balances, hotplate stirrers, syringe pumps, spectrometers, potentiostats and other instruments. Each server checks commands against user-set safety limits and logs them, and each has a practice mode. The README marks all 32 as tested only in simulation, from the makers' manuals.

EmbeddedCI's BenchPod plugins connect Claude Code and Codex to a BenchPod, the company's hardware-in-the-loop tester wired to the board under test. One MCP server has tools to flash over SWD, power-cycle and capture the boot log, emulate I2C sensors, capture logic and analog signals and talk CAN. The vendor README lists the tools but shows no runs.

platformio.mcp exposes PlatformIO to coding agents as 40 MCP tools in a Python server. Besides builds and serial or OTA flashing, it decodes ESP32 and Cortex-M crash backtraces, reads core dumps, checks partition tables and runs GDB sessions. Its flash-and-verify tool reads the boot log until an expected line or a crash appears. The README shows no board captures.

embedagents-stm32 runs ST's own command-line tools from Claude Code to work on STM32 projects. It drives CubeMX, CubeIDE, CubeProgrammer, the signing tool, the ST-LINK GDB server and the virtual COM port, and bundles none of them. The README's demo GIF shows Claude Code building and flashing a NUCLEO-L476RG from one plain-language request.

Sigurd Enghoff replaced the WLKATA MT4 desktop arm's stock firmware and built a vision and MCP control stack on top. His ATmega2560 firmware runs Cartesian moves on the arm, ArUco markers calibrate a fixed camera, and an MCP server takes requests from Claude Code or Cursor. Linked videos show the arm stacking cubes and following typed instructions.

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.

Craig Hollabaugh had Claude Code boot Linux overnight on an Icepi Zero, a Lattice ECP5 FPGA board with no hard CPU. The agent installed LiteX and built a VexRiscv soft core that boots OpenSBI, Linux 5.14 and BusyBox to a root shell over USB serial. The 10-minute video logs into the running system on the board.

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.

Claude Code wrote serial scripts for the STS3215 servos of a self-assembled SO-101 arm and fixed GR00T N1.6-3B fine-tuning errors for a Japanese maker. It set motor IDs, showed live gripper values and ran training over SSH on a DGX Spark. After 97 recorded episodes, the post's GIF shows the arm placing a block in a cup on its own.

Norihide Mikami used Claude Code with Opus 4.7 to write a Flask control system for a DENSO six-axis arm in one 4.5-hour hackathon session. It drives the arm over b-CAP, an IAI electric gripper over Modbus RTU, a 4K Basler GigE camera, a webcam and a PS5 gamepad. The three-minute video shows the system running.

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.

Session Beacon shows every Claude Code session on a 1.8-inch ST7735 screen and turns a row red when that session waits on a prompt. A Python daemon fed by Claude Code hooks sends updates over USB serial to an Arduino Nano ESP32 or a Waveshare RP2040-Zero. Setup is documented for Windows only. README photos show the finished beacon.

Sergio Marin built a flash lab in which an Orange Pi 3 LTS controls a Raspberry Pi Compute Module 5 for a coding agent. Through transistors it presses the power button and sets the boot mode, and it handles USB flashing and the serial console. He writes that clean flashes exposed a Wi-Fi bug a saved profile had hidden.

XDA's Anurag Singh used Claude Code to plan an ESPHome multi-sensor on an ESP32-WROOM-32 DevKit. It put an LD2410C mmWave sensor on UART pins and a BME280 and BH1750 on shared I2C pins, then wrote, validated and compiled the YAML. He says the device then reported to Home Assistant. The article shows screenshots, not the build.

One maker had coding agents build IRIS, a robot face with gaze-tracking eyes, on two Teensy boards and a Raspberry Pi 4. Its speech and vision models run locally. Over 195 sessions, one AI planned each change, a second critiqued it and a coding agent made and checked it over SSH. The README shows no photos of the robot.

HARDWARIO published a repository on 30 June that holds its TOWER IoT kit's protocol, STM32L083 firmware, CLI, flasher and hardware-in-the-loop bench. It began as a Claude Code control plane over submodules and is now a Rust monorepo with agent instructions. The README says bench runs flash a physical Core Module and measure power with a PPK2.

Nordic Semiconductor released 2 MCP servers that connect coding assistants such as Claude Code to its SDK and cloud. The Nordic MCP server adds documentation search, an nrfutil reference, a UART monitor script and SDK workflow commands. The nRF Cloud server reads fleet data such as logs and coredumps, without write access. The post shows no hardware runs.

Linutronix describes an off-the-shelf AI agent that tests embedded boards in its lab through a small MCP server. In the example session the agent reserves a board, flashes it, reads the console and power-cycles it after a bad flash. The post argues that the safety comes from the lab underneath. It shows one screenshot and no logs.

H2Loop launched Hydron on Hacker News, an embedded coding agent for VS Code and the terminal that answers from pre-indexed datasheets. The launch post lists more than 580 indexed platforms and peripherals, including STM32, ESP32 and RP2040 parts. An agentic serial monitor shipped at launch; GDB integration and a log reader were promised within 2 weeks.

Ricardo F. Tafas Jr of Espressif describes building Zephyr provisioning over BLE and SoftAP for the M5Stack ESP DualKey with Cursor. He tested each step on the bench through build, flash and UART traces. His practices include specs first, proving a module in a sample app, a journal of failed fixes and no edits to upstream Zephyr.

Tech-AD-venture's 65-minute video walks through wiring sensors to an ESP32 over I2C and UART and defining a JSON command protocol on the serial link. It then builds a FastAPI-based MCP server so an LLM called through the OpenAI API can read registers and send commands. We have not watched the full video to confirm the hardware segments.

Ricardo F. Tafas Jr of Espressif explains how he built Rust firmware for an ESP32-S3-based M5Stack ESP DualKey, with Cursor's agent writing the code. The device handles Wi-Fi, BLE and provisioning. He fed UART traces back to the agent and stepped through with OpenOCD and GDB when its reasoning stalled. Photos show the board's red and green status LEDs.

Seif Salama built an Ackermann-steered robot that runs one ROS 2 Humble stack in Gazebo Harmonic and on a Raspberry Pi car. A custom ros2_control interface drives the motors over UART and the steering servo over I2C. A Gemini or Ollama agent takes spoken commands. We could not tell whether the README video shows the physical robot.
