LabWired The easy way to build hardware
Blog & Whitepapers

Notes from making hardware easy.

Virtual boards you can run in the browser, hand to an agent, and gate in CI — open source, deterministic, no silicon on the critical path.

Building a Complete OBD-II Scanner Without a Car or Hardware

Build and verify a two-MCU nRF52840 OBD-II scanner with MCP2515 CAN, an SSD1306 display, BLE telemetry, and a deterministic virtual vehicle ECU.

CRA secure-boot evidence in CI

Use LabWired to produce CRA-style secure-boot evidence: run real firmware on a virtual board in CI, assert boot/OTA/anti-rollback, and download a signed pack each green run.

Simulating a cellular modem and MQTT without a full network

How LabWired models Quectel AT MQTT (QMT*) and GNSS so firmware can send location messages and you can collect them in the lab, without a radio, SIM, or broker.

Why your AI agent needs virtual, auditable hardware

Agents write firmware but cannot prove it runs. They need virtual, auditable hardware: open-source LabWired boards under MCP, same oracle in Playground and CI.

Running a full IO-Link master with no hardware

A real IO-Link master stack and real device stacks, talking over the C/Q wire, with the whole exchange running in software, in your browser and in CI. Nothing mocked.

Render your Arduino e-paper firmware without the hardware

Build a real Arduino-ESP32 GxEPD2 e-paper firmware with PlatformIO and run the same ELF inside the LabWired simulator. It paints a simulated panel exactly as the real one.

Catching a CAN bug that only shows up on real hardware, with LabWired

A multi-frame UDS (ISO-TP) bug that only surfaced on real STM32F103 hardware (an N_Cr clock-source mismatch), reproduced, debugged, and fixed in LabWired without touching the silicon.
