Product description
Waveshare Barcode Scanner Module (D) - Compact Module for Barcodes and QR Codes. A powerful and compact module for decoding both 1D and 2D codes (e.g., barcodes, QR, DataMatrix, etc.). Thanks to its high level of integration, simple interface, and LED indicator, it provides a convenient solution for automated scanning in embedded systems and industrial applications. Supplied with two connection cables: 6-pin connector to open end and 6-pin connector to 6x female Dupont.
Specifications:
