## Description

Optical module for fast and accurate scanning of 2D codes, barcodes and QR codes, ideal for Arduino projects and automation. Reads omnidirectionally, including codes on curved surfaces, works continuously or at the press of a button. Connects via USB or UART and can add prefix or suffix, the white LED illuminates the code and the buzzer confirms the reading.
Quality module for scanning and identifying 2D images, barcodes and QR codes. It is compatible with Arduino and other development boards.
Regardless of the type of code scanned, the sensor can scan omnidirectionally and allows scanning even codes folded on round objects.
The module can be set up in multiple ways, such as scanning on button pass or continuous scanning. Prefixes or suffixes can be added to scanned codes and multiple terminals can be selected.
Communication can be achieved both via USB and via virtual serial port. Used directly via the USB port connected to the computer, the functionality can be tested by opening a document (Word, Excel, etc...) and when scanning barcodes or QR codes, the read information will be automatically written to the document.
The button allows manual scanning and the integrated buzzer announces the reading. It also integrates a White LED to illuminate the read code.
