M5Stack Atomic Barcode/QR-Code Scanner 2 Base

The Atomic QRCode2 Base from M5Stack is a compact 1D/2D barcode scanner specifically designed for the ATOM series. The module supports three common 2D code types (QR Code, PDF417, Data Matrix) as well as 14 different 1D barcode formats. An integrated 640×480 CMOS sensor enables high-resolution image capture with a reading accuracy of at least 5 mil. The built-in buzzer provides acoustic feedback during various operating states. A red LED assists with focusing and aiming, while a white LED ensures adequate lighting. Communication occurs via UART at 115200 bps, allowing scanned data to be easily transmitted to the ATOM controller. The back is equipped with magnets, M3 screw holes, and mounting holes. This module is ideal for logistics, retail, and manufacturing applications where fast and reliable scanning is required.
