Install umbravox

Connect your board by USB. Choose its exact model, connect, then install. No compiler or command line required. Use desktop Chrome or Edge.

1. Choose your board

Choose your handheld or XIAO ESP32-C5 scanning node. Select the exact hardware; these firmware images are not interchangeable.

I selected the exact board and understand this installs the selected firmware and partition layout. I have backed up anything needed from internal flash.

First installation replaces the partition table with two 6 MiB application slots. Existing internal filesystem data may become inaccessible. External SD files are not written. No full-chip erase is performed.

Select a board to begin.

Prefer the command line? The download includes instructions for esptool 5.6.0. After installation, press RESET and enroll the node from your handheld.

If the board will not connect

Use a USB data cable and close other serial monitors.
Hold BOOT, press and release RESET, then release BOOT.
Click Connect and select that board’s serial port. NM uses its CH340 USB connection.

Installation does not restart the board automatically. After all four images verify, press RESET (without holding BOOT) to start it.

Waveshare 2.8″ and 3.5″ browser installation and boot are confirmed. NM-CYD-C5 flashing and operation are confirmed; full feature validation remains open. This is a public beta. See the release notes for tested features and known limitations.
