Description Module13.2 QRCode is a 1D/2D barcode scanning module from the M5Stack stacking module series. It integrates a 640 x 480 CMOS barcode capture engine for fast recognition of codes printed on paper, labels, tickets, and packaging. The module supports three mainstream 2D code types and fourteen common 1D code types. A hardware switch selects USB or UART communication, and the USB interface supports virtual serial port, HID keyboard, and HID-POS modes for connection to different host systems. With built-in buzzer feedback, white illumination LED, red aiming LED, multiple trigger modes, and DC 9 ~ 24V input, Module13.2 QRCode is suitable for logistics, retail checkout, production traceability, medical information collection, ticketing, and self-service terminals. Features Module13.2 QRCode scanner: compact M5Stack stacking module for 1D and 2D barcode recognition. Code support: reads PDF417, QR Code, Data Matrix, and fourteen listed 1D code formats. Dual communication: USB or UART selection through the onboard switch. USB operating modes: supports virtual serial port, HID keyboard, and HID-POS modes. Scan feedback: integrated buzzer, white illumination LED, and red aiming LED. Trigger flexibility: supports auto, continuous, motion sensing, pulse, and other scanning trigger modes. Wide DC input: DC power input supports 9 ~ 24V through the onboard step-down circuit. Development support: Module13.2 QRCode works with Arduino and UiFlow2 resources.
