SiteSurvey Pro

Web Installer — Guition NM-CYD-C5 (ESP32-C5)

firmware v…

Web Serial isn’t available here — open this page in desktop Chrome or Edge over HTTPS.

Flashing takes about a minute. The board reboots into SiteSurvey Pro when done.

What you need

A Guition NM-CYD-C5 board and a data-capable USB–C cable
Desktop Chrome or Edge (Web Serial; Firefox and iOS are not supported)
Windows only: the CH340 USB–serial driver (usually already installed)

Steps

Plug the board into your computer.
Click Connect & Flash and pick the board’s serial port.
Accept the erase prompt on a first install.
Wait for the progress bar to finish — the device resets and boots into the survey UI.

Troubleshooting

No port in the list? Re-check the cable (charge-only cables are the usual culprit) and the CH340 driver.
Connect fails? Hold the BOOT button on the board, click Connect, release BOOT once flashing starts.
Prefer the command line? The same binaries flash with esptool.py — see the README.
