Free Web Serial Terminal
Use a normal UART terminal first.
Capture, paste, or upload a boot log. Running a preview sends the log to our analysis servers so the CVE matcher and detector suite can run; logs are only persisted when you sign in and save them to your fleet. For a fully local, no-upload fingerprint (bootloader / kernel / CPU only), use the fingerprint tool instead.
Enabled once a log has been captured, pasted, or uploaded.

Web Serial is available in Chromium-based browsers. You can still paste or upload logs below.
Use 3.3V UART logic, connect GND/RX/TX only, and try 115200 8N1 first. Garbled output usually means the baud rate is wrong.
No terminal output yet
Connect a serial adapter, paste a log, or upload a boot log file.
