M5Stack QR Code Scanner Unit (STM32F030)

Description QR Code Scanner Unit (STM32F030) Versatile I2C/UART interfaces Decodes multiple barcode types High-res 640x480 CMOS sensor Configurable scanning modes Compact design: 65.8 x 18.4 x 15.8 mm The QR Code Scanner Unit (STM32F030) is a sophisticated code scanning unit that incorporates a CMOS QR code capture engine with a resolution of 640x480, alongside a bus conversion microcontroller unit. This device is equipped with a toggle switch on the side, enabling the user to select between I2C and UART communication interfaces with ease. This module is adept at decoding three prevalent QR code types and eight varieties of one-dimensional barcodes commonly encountered in the market. Additionally, it is designed with a scan trigger button, an internal buzzer, and supplementary LED lighting to facilitate the scanning process. The buzzer and green LED emit auditory and visual signals respectively, which aid in focusing and targeting during scanning operations. Configura
