Desert EdgeTruArc Firmware
CHECKING RELEASE…
Browser installer

Update the field computer. Not your blood pressure.

Connect TruArc by USB and install official firmware directly from this browser. Nothing is uploaded from your device.

Do this first

Your data

Saves your rifles, loads, locations, cards and stage sheets to a file on this computer, straight off the device. Works on any TruArc, including shipping firmware. Take one before you install anything.

Connect TruArc by USB, then choose SAVE MY DATA.

The file is plain CSV — open it in a spreadsheet and read it. Restoring never happens behind your back: the device shows what it is about to change and you press the button on its screen.

Recommended

Update firmware

Writes only the application image. Leave Erase device off to preserve stored data when the release uses the same storage schema.

Four-minute procedure
  1. Save your dataUse SAVE MY DATA above before you install. It takes seconds and it is the only copy you will have if something goes wrong.
  2. Connect USBUse a data-capable USB-C cable. Close Arduino Serial Monitor or anything else using the port.
  3. Choose the portSelect the USB serial device when your browser asks. Hold BOOT only if connection fails.
  4. Keep it connectedDo not unplug or close the tab until installation completes and TruArc restarts.
Before you start: use Update for normal releases and leave Erase device off. Byte preservation cannot rescue incompatible storage-schema changes; release notes must identify migrations. Factory install may erase all device data. This installer accepts only official TruArc builds—not Impact Mini or unrelated devices.
