HF·NODE puts AI on your bench. It knows when your board is wedged vs. dead, catches power conflicts your firmware can't see, and reflashes bricked targets over the debug port — so your coding agent can run embedded dev unattended. External debug device for embedded boards — no SDK, no code changes. Watch GPIO, ADC and power rails, read CPU and register state, track device life state, catch firmware that runs wrong without crashing, and push OTA with rollback from anywhere.
