Waveshare Barcode Scanner Module, 1D/2D Codes Reader Module, PH2.0-4Pin UART / micro USB Interface, Can Work in the Dark WS0252

Overview:
This is a small 1D/2D codes reader, by using the intelligent image recognition algorithm, it will decode the barcode or 2D code on paper or screen, fast and accurately.

Through the onboard USB and UART interface, it can be directly plugged into a computer, or be easily integrated to kinds of devices due to its small form factor.

Features:
Easy to use, requires no knowledges of image recognition
Decodes various common 1D/2D codes such as Barcode, QR code etc.
Onboard micro USB and UART serial port, allows to connect with computers or embedded devices
Configurable via scanning 'configuration code'
Onboard light source, works in the dark

Specifications:
Operating voltage: 5V
Operating current: 135mA (scanning), 58mA (standby), 2mA (sleep)
Operating temperature: 0°C~60°C
Operating humidity: 5%~95% (Non-condensing)
Communication interface: UART, USB
Decodes 1D codes: Codebar, Code 11, Code 39/Code 93, UPC/EAN, Code 128/EAN128, Interleaved 2 of 5, Matrix 2 of 5, MSI Code, Industrial 2 of 5, GS1 Databar(RSS)
Decodes 2D codes: QR code, Data Matrix, PDF417
Light source: white
Scan angels: roll 360°, skew ±65°, pitch ±60°

Hardware Connection:

This module supports two communicating interfaces. You can connect the USB
interface to your device with micro USB cable. Or you can connect the UART interface
to your device.
If you want to test the UART interface with PC, you need prepare an TTL to
USB board CP2102  yourself.
