Unit QRCode is an integrated 1D/2D barcode scanning unit, internally equipped with a 640x480 resolution CMOS barcode scanning engine and a bus conversion MCU (STM32F030). By toggling the side switch, it can switch between I2C and UART communication interfaces. The scanning engine supports 3 types of 2D barcodes and 8 types of 1D barcodes prevalent in the market, and comes with a firmware upgrade interface. The unit features a scan trigger button, a built-in buzzer, and a fill light LED, providing audio cues in different states. A red LED is used for focus and aiming assistance. It can be programmed to operate in either automatic continuous trigger or manual trigger mode. Suitable for logistics, retail, manufacturing, and other fields.
