Component	Latest	Downloads	Changelog
Scanner Firmware		Firmware binaries	Scanner changelog
Middleware		Source	Middleware changelog
Installer		Source	Installer changelog

Quick Install

The installer downloads the latest firmware automatically:

curl -sL https://raw.githubusercontent.com/SpoolSense/spoolsense-installer/main/install.sh | bash

Firmware Binaries

Each scanner release includes pre-built firmware for all three boards:

File	Board
spoolsense_scanner_esp32dev.bin	ESP32-WROOM DevKit
spoolsense_scanner_esp32s3zero.bin	ESP32-S3-Zero
spoolsense_scanner_esp32s3devkitc.bin	ESP32-S3-DevKitC-1

Plus matching bootloader and partition table binaries. The installer handles flashing all of these automatically.

As of v1.8.3, each binary also ships with a matching .sha256 sidecar file so you can verify a manual download (for example, shasum -a 256 -c spoolsense_scanner_esp32dev.bin.sha256).

Updating

• OTA: Open http://spoolsense.local/update to check for and install updates over WiFi
• USB: Re-run the installer with your ESP32 connected
• Middleware: cd ~/SpoolSense && git pull and restart the service
