We built Ferqon because flashing boards by hand doesn't scale. A team we know was shipping an RP2040 product — 50 boards, each needing firmware flashed and 12 commands verified. Their process: plug in, flash, open a serial monitor, eyeball the response, log it in a spreadsheet, repeat. Two engineers. Three days. Two boards failed in the field — one from a response that was slightly off-spec, one from the wrong firmware binary. No way to trace what happened. Ferqon turns that into one click. It's a hardware-in-the-loop testing platform that runs on a Raspberry Pi: Auto-detect connected devices Flash the right firmware every time, with version tracking Run test sequences — send commands, validate responses, pass/fail automatically Full traceability — every board, every firmware version, every result, logged That same 50-board batch now finishes in under an hour. No spreadsheets, no guesswork. It's local-first: no cloud dependency, no telemetry, your data stays on your Pi. Open a browser, build your test sequence, hit run. Curious — what does your firmware testing workflow look like right now? Are you running something custom, or still doing it by hand?
