GROW GM861S Barcode Scanner 3.3V 70mA Module
The GROW GM861S Barcode Scanner Module is a miniature high-performance barcode scanning engine capable of reading both 1D and 2D barcodes with fast and accurate decoding. Equipped with a 640 × 480 CMOS image sensor, it supports popular barcode formats including QR Code, Data Matrix, PDF417, Code128, EAN, UPC, Code39, and many others. Its compact size and lightweight design make it ideal for integration into handheld devices, vending machines, self-service kiosks, access control systems, and embedded industrial equipment.
The module operates from a 3.3V supply and communicates through TTL-UART or USB, making it easy to interface with microcontrollers, single-board computers, and embedded controllers. With a fast startup time, wide scan angle, and reliable decoding performance, the GM861S provides an excellent solution for compact barcode scanning applications where space, power consumption, and performance are important.
