Description
QRCode Unit is an integrated one-dimensional/two-dimensional code scanning unit that combines a CMOS QR code capture engine with a resolution of 640×480 and a bus conversion MCU (STM32F030). It features a device-side toggle switch that allows for switching between I2C and UART communication interfaces.
The capture engine supports three types of mainstream QR codes and eight types of one-dimensional codes found in the market. It also provides a firmware upgrade interface. The unit includes a scan trigger button, a built-in buzzer, and supplementary LED lights. The buzzer and green LED provide audio and visual cues in different states, assisting with focusing and aiming.
The QRCode Unit can be configured through programming to operate in automatic continuous trigger or manual trigger mode. It is suitable for various fields such as logistics, retail, and manufacturing where barcode scanning is required.
To switch to UART serial communication mode, ensure the device is powered off, toggle the mode switch to the UART serial position. Then, press and hold the TRIG button for 2 seconds while powering on until the device completes startup to successfully switch to UART serial communication mode. If you have any questions, feel free to contact technical support.
