Description
Description Unit QRCode is an all-in-one 1D / 2D code scanning unit, integrating a 640x480 resolution CMOS QR code capture engine and a bus conversion MCU (STM32F030). By toggling the side switch on the device, users can switch between I2C and UART communication interfaces. The capture engine supports 3 mainstream types of QR codes and 14 types of 1D codes on the market, and reserves an interface for firmware upgrading. The unit features a scan trigger button, built-in buzzer and fill-light LED, providing audio prompts in different states. A red LED is used for auxiliary focusing and aiming. Through program settings, it can be configured for automatic continuous triggering or manual triggering mode. Suitable for logistics, retail, manufacturing, and other fields.
