Every software project has CI. Hardware projects still have someone manually hitting "Upload" in the IDE and squinting at the serial monitor.

nff fixes that. It's a Python tool + MCP server that exposes your board as callable functions:

  • nff flash ./sketch.ino — compile and upload from the CLI
  • nff monitor — scripted serial capture
  • nff init — auto-detects your board by USB vendor ID, no config needed

You can script it, pipe it, schedule it. Uno, Mega, Nano, ESP32, ESP8266 supported out of the box. Adding a board is two lines.

pip install nff
