QR Code Scanner Module 13.2

The Module13.2 QR Code is a fast, reliable 1D/2D barcode scanner with a 640×480 CMOS sensor that reads 3 common 2D and 14 1D codes. It connects over USB or UART (selectable by switch) and includes a buzzer, aiming and light LEDs, plus trigger options for auto, continuous, motion, or pulse modes. Powered by DC 9–24V, it’s a solid choice for retail, logistics, ticketing, and factory use.

Module 13.2 QR Code is a 1D/2D barcode scanning module from the M5Stack stacking module series. It integrates a CMOS barcode capture engine with a resolution of 640 x 480, supporting 3 mainstream 2D code types and 14 1D code types on the market, enabling fast and accurate recognition of barcodes printed on media such as paper and labels. A toggle switch allows switching between USB and UART communication interfaces for the QR module to communicate with external devices. The USB interface can be configured in three modes: USB virtual serial port, USB HID keyboard, and USB HID-POS. The module features a built-in buzzer for audio prompts, illumination and aiming LEDs, provides rich secondary development interfaces, and supports multiple scanning trigger modes (e.g., auto mode, continuous mode, motion sensing mode, pulse mode) for customized functionality and integrated development. It integrates a DC power input interface supporting DC 9 ~ 24V. Through the internal DC-DC step-down circuit it powers the entire device, making it suitable for logistics and warehousing, retail checkout, ticketing systems, production traceability, medical information collection, self-service terminals, and many other scenarios.
