What We're Building

Everything you need to work with real hardware, remotely.

Remote access to real MCU boards. Flash, debug, and test from your browser, CLI, or CI pipeline.

01

Remote Flashing

Upload firmware and flash ESP32-S3 boards over the air via esptool. No USB cable, no physical access needed.

02

Live Serial Console

Full interactive serial terminal in your browser, powered by WebSocket and xterm.js. Just like plugging in locally.

03

Power Cycling

Per-port USB power control lets you hard-reset boards remotely with a single click. No more asking someone to unplug it.

04

CI/CD Integration

GitHub Action for hardware-in-the-loop tests. Flash, run, assert on real hardware, right in your pipeline.

Roadmap

Where we're headed.

More MCU Families

Custom Sled PCB

FPGA-based test sled for GPIO and signal capture.

Instrument Access

Logic analyzer and power profiling from your browser.

Teams & Orgs

Role-based access, shared boards, usage dashboards.

Early Access
