Adhesive Compact Barcode / 2D Code Reader (USB-C)

Adhesive Compact Barcode / 2D Code Reader (USB-C)

A compact barcode reader for smartphones using the GROW GM805 module.

Enables standalone POS and inventory management applications on a smartphone.

Most commercial barcode readers use Bluetooth, but no USB-C connected ones were available, so I built my own. With USB-C direct connection instead of Bluetooth, no setup or charging is needed, providing low-latency and stable reading.

Features

• USB-C direct connection — No Bluetooth pairing or charging required
• Adhesive mount — Sticks to the back of a smartphone case
• 1D/2D code support — Reads barcodes, QR codes, and more
• 3D printed case — Ultra-compact original enclosure
