Description The M5Stack Atomic QRCode2 Base is a compact barcode QR code scanner base for ATOM series hosts and embedded data-capture projects. SKU M5-A133-B is designed as a small 1D 2D barcode scanner and UART scanner module for inventory scanning, retail scanning, logistics labels, kiosk verification, manufacturing traceability, and portable automation tools. This M5Stack Atomic QRCode2 Base integrates a 640 x 480 CMOS@M14 scan module, white illumination LED, red focus and aiming LED, and buzzer feedback inside a compact PC housing. The scanner reads PDF417, QR Code, Data Matrix, and common 1D barcode formats, so one barcode QR code scanner can handle QR code scanning, 2D code scanning, and standard barcode scanning workflows. The UART scanner module communicates through UART@115200, making the M5Stack Atomic QRCode2 Base straightforward to integrate with ATOM hosts and other embedded controllers. Rear magnets, M3 screw holes, and LEGO-compatible mounting holes make the 1D 2D barcode scanner easy to install in fixtures, handheld scanners, smart cabinets, access-control kiosks, and warehouse scanning prototypes. Features M5Stack Atomic QRCode2 Base: compact ATOM base barcode QR code scanner for embedded scanning and data collection. 1D 2D barcode scanner: supports PDF417, QR Code, Data Matrix, and 14 common 1D barcode formats. UART scanner module: UART@115200 interface keeps integration simple with ATOM hosts, ESP32 controllers, and serial data systems. 640 x 480 CMOS module: CMOS@M14 scan module supports reliable code recognition in compact installations. Built-in aiming and feedback: white illumination LED, red focus and aiming LED, and buzzer feedback help scanning operation. Flexible mounting: rear magnet, M3 screw holes, and LEGO-compatible mounting holes support kiosk, fixture, and mobile mounting. Compact PC housing: 48 x 24 x 17.5mm scanner base is suitable for small scanning devices and embedded barcode readers. A133-B integration path: useful for inventory scanner, retail QR code scanner, warehouse barcode scanner, and manufacturing traceability scanner projects.

Retail scanning prototypes for shelf labels, ticket codes, loyalty QR codes, and customer payment QR code scanning. Warehouse barcode scanner fixtures for logistics labels, package tracking, bin labels, and asset identification. Manufacturing traceability stations for work-order labels, batch codes, serial numbers, and production line scanning. Kiosk scanning, access control, ticket validation, smart cabinet, and embedded data-capture systems. Product List 1 Atomic QRCode2 Base Other Content Integration note: The M5Stack Atomic QRCode2 Base is a base module. Confirm ATOM host compatibility, UART wiring, 5V power, mounting direction, scan distance, ambient light, and code size before installing the barcode QR code scanner in a fixture. Scanning note: The 1D 2D barcode scanner supports multiple 1D and 2D code families, but final reading distance depends on code size, print quality, contrast, lens angle, and lighting. UART note: The UART scanner module outputs decoded barcode data over UART@115200. Validate AT commands, trigger behavior, and host-side serial parsing before deployment. Mounting note: The rear magnet, M3 screw holes, and LEGO-compatible holes make A133-B suitable for quick scanning fixtures, handheld readers, and compact embedded barcode reader prototypes. Selection note: Choose the M5Stack Atomic QRCode2 Base when a project needs a small UART barcode QR code scanner rather than a large handheld scanner body.
