QR Barcode Scanner 1D 2D QR Code Reader TTL/USB/RS232 interface Barcode Scanner Module

This module is a portable, highly integrated, and excellent-performance embedded QR code/barcode scanning module. The module has a protective lens, which is beautiful and generous. The module is easy to use, without programming, and provides the serial port output and USB output (serial port also includes TTL output and RS232 output interfaces directly connected to the single-chip microcomputer), serial port transparent transmission can directly communicate with various single-chip microcomputers (such as stm32, Arduino-compatible board, 51 single-chip, Raspberry Pi, etc.). The USB interface can be directly connected to the computer for testing, no need to install the driver, and the result can be scanned as long as it is placed at the text cursor position. This module has a supplementary light, can work in a completely dark environment, has consistent scanning performance over a large temperature range, and can normally work under harsh conditions such as shock, vibration, and strong exposure.   Pin Description Pin Input/Output Name Description Color 1 Power 5V 5v power supply Grey 2 Ground GND Ground Purple 3 Input TTLRXD TTL serial port RXD, connected to MCU TXD Blue 4 Output TTLTXD TTL serial port TXD, connected to MCU RXD Green 5 Two-way D- USB D-signal Orange 6 Two-way D USB D signal Yellow 7 Output Beep Buzzer White 8 Output 232_TXD 232 serial port TXD Red 9 Input 232_RXD 232 serial port RXD Black *Adopt 1mm spacing socket interface, socket specification “SH1.0”   Feature Portable, highly integrated, excellent performance QR code scanning module Fast scanning speed, high precision, can scan a variety of barcode formats Easy to use, no programming required, serial port and USB output are provided   Specification Light Source: LED White Light Scanning element type: CMOS Recognition barcode accuracy: ≥10mil Scan resolution: 640*480 Pixel camera: 300,000 pixels Supports QR code medium: Screen and Paper Barcodes Support Barcode type: QR Code, Data Matrix, PDF417, Code 128, EAN-8, EAN-13, Interleaved 2 of 5, UPC-A, Code 39, UPC-E Contrast: ≥30% Scan angle: Rotate 360°, tilt ±60°, deflect ±60° Scanning speed: 98 times/second Communication method: Wired communication Interface: USB, Serial port Prompt way: Buzzer Scan mode: Automatic trigger (trigger mode can be set) Operating Voltage: 3.3-5VDC±10% Working current: 44mA±5%(Typical); 50mA±5%(Max) Sleep current: 31-51mA Power consumption: 116-223MW Operating temperature: 0~50℃ Storage temperature: -20~60℃ Dimensions: 64.9*65.8*25mm Net weight：35g   Package List 1xQR Code Scanner Module 1x SH1.0 Cable
