NFM23 DIY Barcode Scanner Engine 

DIY Barcode Scanner Module NFM23 is a new generation 2d barcode scanner module that can decode poor-quality barcodes swiftly and effortlessly. and it can work with the raspberry pi and Arduino board. 



High Performance & Ultra-Low Power Consumption: The engine can read 1D and 2D barcodes with power consumption, it’s a high performance and low power consumption module.

All-in-One Design: image sensor and decoder board make the scan engine small, lightweight, and easy to fit into even the most space-constrained equipment like handheld terminal PDAs, and tablet terminals.

Multiple Interfaces: support TTL-232 12pin serial communication methods, or USB to meet diverse customer needs.

Application Scenarios (as an accessory)

The mini size is better for OEM 1D/2D barcode scanner products, widely application used in traditional self-service devices, PDAs, tablet terminals,  handheld mobile computers, lottery terminal machines, Bluetooth ring scanners, Bluetooth pocket scanner, door locks, and other thin & light mobile devices
