This CM65 code scanner module can accurately read the barcode or QR code on paper or screen at high speed (about 1s) even in the poorly-lit environment.
By using the intelligent image recognition algorithm, this module can easily decode all kinds of common 1D/2D codes. Through the onboard micro USB and UART interface, it can be directly plugged into a computer or integrated to various devices. The module is configurable via scanning ‘configuration mode’ so as to meet some strict scanning requirements. Besides that, with an onboard light source, this scanner can work well even in the dark and provide consistent scanning performance in the extreme temperature range.
This module can be easily embedded into multi-medium barcode scanning equipment, including self-service vending machine, subway gate machine, access control, payment machine, etc.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
