M5Stack U173 QRCode Unit
M5Stack U173 QRCode Unit is an integrated one- or two-dimensional code-scanning unit with a device-side toggle switch that enables switching between I2C and UART communication interfaces. This unit combines a CMOS QR code capture engine with a 640x480 resolution and a bus conversion microcontroller (STM32F030). The U173 QRCode unit includes a built-in buzzer and a lighting LED. The unit can be configured through programming to operate in manual trigger or automatic continuous trigger mode. The U173 unit consists of a QRCode unit and HY2.0-4P (20cm). This QRCode unit is ideal for logistics, retail, and manufacturing sectors where barcode scanning is required.
