Basic Information
Product Description

This is a megapixel two-dimensional scanning engine, which has very leading product performance of similar products, and can work stably and uninterrupted for a long time. The integrated development of RD11P is very easy, and the company provides complete development documents. Provides trigger scan working mode, provides LED and Buzzer indication interface, which can almost meet any application of your regular one-dimensional and two-dimensional scanning requirements.

QR Codes Scanner Features:
* High Performance & Ultra-Low Power Consumption:
The engine can read 1D and 2D barcodes with a power consumption only one third that of a traditional engine.
* All-in-One Design:
Seamless integration of image sensor and decoder board makes the scan engine small, lightweight and easy to fit into even the most
space-constrained equipment.
* Multiple Interfaces:
The RD11C support TTL-232 12pin serial communication methods,or USB to meet diverse customer needs.
