{"product_id":"qr-code-scanner-unit-stm32f030","title":"QR Code Scanner Unit (STM32F030)","description":"\u003cp\u003eThe QRCode Unit is a simple yet effective scanning device, combining a CMOS QR code capture engine with a 640 x 480 resolution and a bus conversion MCU (STM32F030). It includes a switch for alternating between I2C and UART communication interfaces.\u003c\/p\u003e\n\u003cp\u003eThis unit can read three common types of QR codes and eight types of one-dimensional barcodes. It features a firmware upgrade interface for added convenience. It has a scan trigger button, a buzzer, and LED lights, which help in indicating different states and assist in scanning.\u003c\/p\u003e\n\u003cp\u003eYou can set up the unit to work in either an automatic continuous trigger mode or a manual trigger mode, based on their needs. It's a practical tool for areas like logistics, retail, and manufacturing, where barcode scanning is a regular activity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: To switch to UART serial communication mode, ensure the device is powered off, and 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.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSTM32F030F4P6@32 bit ARM Cortex-M0 processor\u003c\/li\u003e\n\u003cli\u003eSupports 3 types of two-dimensional code and 8 types of one-dimensional code\u003c\/li\u003e\n\u003cli\u003eUpgradable firmware\u003c\/li\u003e\n\u003cli\u003eBuilt-in I2C and UART communication interface switch\u003c\/li\u003e\n\u003cli\u003eBuilt-in buzzer sound prompts\u003c\/li\u003e\n\u003cli\u003eBuilt-in lighting LED\u003c\/li\u003e\n\u003cli\u003eHigh-resolution imaging\u003c\/li\u003e\n\u003cli\u003eFocusing and aiming functions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"812\" style=\"height: 287px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"height: 19px;
