Description
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.
