This scanner reads barcodes or 2D codes with a scan speed of 15m/min. With its small size and high-efficiency recognition, it is easy to be integrated into various industrial equipment and applications.
The module is equipped with a 0.3megapixel camera and auxiliary lights, white light illumination, and red light focusing, which makes it able to effectively identify codes in low-light environments.
The module automatically senses and scans, identifying the surrounding environment. Once auto-triggered, it quickly recognizes and reads code. The scanner also has TTL-232 and USB two communication interfaces for more actual scenarios.
