Show HN: Nff_ – open-source bridge between agents and 1000+ different boards

I am an embedded engineer, and tried Claude Code recently, I wanted to have the experience of Claude coding on real hardware boards, whatever the processors, whatever the compilers, whatever the toolchains.

Honestly, this is a Platform IO wrapper MCP tool with extra steps. I added reliability to it, made it rust based, and made it open source. The onboarding is quite easy as well : you just run 'pip install nff' in your favorite ide, connect your board, then run 'nff init', it detects your board, and the COM port communicating with it.

To use it then, its just basically running claude code or codex on your board : plan features, and watch them get build, tools then compile flash and debug instead of you doing the manual work. Saved me a month of work on the integration of a Texas instrument toolchain.

This works with all platformio supported boards including esp32, stm32, nRF, rp, teensy boards...

The repo shows both python and rust. I prototype on Python then migrate on Rust for speed. The binary wheel you are installing is the rust one.

Currently working on OTA capabilities, and a platform that allows this to operate and maintain your iot fleet. Releasing this next week.

What features should I build next ?
