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.

AgentFace32 shows what coding agents such as Claude Code and Codex are doing on an ESP32 board with a small screen. Agent hooks send JSON events over the local network, and the device draws a face, a status line, a task timer and alerts. The README's video shows it following a live Codex session on an M5Stack Basic.

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.

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.
Ranked by points weighed against age. New entries with early votes rise.

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.

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.

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.

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.

Meta open-sourced device SDKs and firmware that connect an ESP32 board or a Raspberry Pi to its Muse app. ESP32 gadgets can show images, handle audio and read sensors; Linux gadgets run custom commands for sysadmin or Home Assistant chores. The README points coding agents to an AGENTS.md in each directory.

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.

adsb-radar decodes ADS-B on a Raspberry Pi Zero 2 W with an RTL-SDR. An n8n workflow on a Raspberry Pi 5 picks the plane visible from a window and looks up its route, and an ESP32-S3-BOX-3 screen shows it. The owner says all the code came from Claude Code sessions. The README reports 4,623 sightings in 12 days.

Synacl's 2.5-minute video shows claude.ai writing a macro that runs on an ESP32 flashed with Synacl's gateway firmware. Claude connects through a custom MCP connector, creates a GPIO device and writes a 5-step macro. Its first run is refused until a person grants 2 permissions; then the board's GPIO 2 LED blinks. Synacl made the demo for its own product.

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.

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.

Creator Magic plugged three unlabeled ESP32 boards into a Mac one at a time and had Claude Code identify each over USB. Claude then wrote different firmware for each: a sea-conditions display, a Bluetooth audio spectrum analyzer and an e-paper sound picture. The 23-minute video shows all three running and a display offset Claude diagnosed from a photo.

XDA's Adam Conway ran the same ESP32 wiring prompt 15 times across Claude Sonnet 5 and Opus 5. With a vague prompt, Sonnet put a display's DC line on strapping pin GPIO2 in 3 of 6 runs, twice after naming the rule. Opus never did, though one run misstated the rule. He writes that naming the exact board helped both.

Niclas Vestlund's VibePulse shows Claude Code and Codex usage and agent activity on a Waveshare ESP32-S3 AMOLED panel. A full-screen alert appears when an agent waits for input, and a tap answers supported prompts. A Python service runs on macOS or Windows; cloud relays are off by default. The README links a YouTube Short of the panels on his desk.

Daniel Frassinelli of Veecle reviewed first-party hardware MCP servers and found that seven chip and tooling vendors shipped them between October 2025 and August 2026. He found no official server from ST, Infineon or Renesas. He writes that none of the vendor servers runs firmware without a physical board; Veecle's own product, Chiplab, targets that gap.

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.
