M5Stack QR Code Scanner Module 13.2

With the M5Stack QR Code Scanner Module 13.2, you can quickly turn your M5Core into a reliable 1D/2D barcode scanner. The module integrates a 640×480 CMOS engine and detects common 2D codes (QR, Data Matrix, PDF417) as well as numerous 1D formats quickly and accurately. A slide switch allows you to choose between USB and UART interface—ideal for flexibly switching between PC operation and direct microcontroller connectivity. Via USB, you have access to Virtual COM, HID-Keyboard, and HID-POS modes, allowing you to use scans either as serial data or as "keyboard inputs." For reliable capture, a white illumination LED and a red aiming LED are integrated, along with a buzzer for acoustic feedback. Multiple trigger modes (Auto, Continuous, Motion Detection, Pulse) adapt to your workflow. Thanks to a wide-range input (9–24 V) and internal step-down, the module can be conveniently powered in stationary applications. Three Grove ports (PORT.A/B/C) simplify expansion and integration into your system. With compact dimensions and lightweight, the module is ideal for smart kiosks, cash registers, manufacturing, and logistics. The robust design ensures reliable scanning even under changing lighting conditions. Through the HID-Keyboard output, you can scan directly into forms, cash register programs, or spreadsheets without additional software. The UART option offers you maximum control in embedded projects.

Features:

Image Sensor: 640×480 CMOS ensures precise capture even of small codes (≥ 5 mil) and at low contrast (≥ 20 percent).
Code Support: Reads QR, Data Matrix, PDF417 as well as many 1D formats like EAN, UPC, Code39/93/128, GS1 Databar, 2-of-5, MSI, and Codabar.
Interfaces: Switchable between USB and UART for flexible connection to PC or microcontroller.
USB Modes: Virtual COM, HID-Keyboard, and HID-POS allow serial output or direct keyboard input without additional software.
Optics and Feedback: White illumination LED, red aiming LED, and integrated buzzer increase reading security and ease of use.
Trigger Modes: Auto, Continuous, Motion Detection, and Pulse modes adapt to different workflows.
Power Supply: DC wide-range 9–24 V (5.5×2.1 mm, center positive) with internal step-down for stable supply.
Capture Range: Working depth about 50–160 mm; Pitch/Skew up to approx. ±55 degrees for comfortable aiming.
Expandability: Three Grove ports (PORT.A/B/C) simplify integration of additional sensors and actuators.

Application Examples:

Contactless check-in of goods in the warehouse or shipping station.
Point of Sale systems in retail with HID-Keyboard output without additional software.
Ticket and access systems at kiosks or terminals.
Traceability in manufacturing with stable continuous scan mode on the line.
Data capture in laboratories and practices for samples and patient labels.
