Atom QR-CODE : the 1D/2D barcode scanner for M5Stack Atom

ATOM QR-CODE is a module for the M5Stack Atom development plateform. As expected by its name, this module is designed for reading the 1D Barcode and 2D QR-codes.

The product is made of two parts:

The scanning module supports 6 kinds of 2D codes and 19 kinds of 1D codes. The effective recognition accuracy of high-resolution CMOS imaging reaches 0.1mm. the module can be adjusted to one of the following reading modes: automatic continuous trigger OR manual trigger.

It also have a built-in:

  • Lighting LED to help in identifying codes even in a dark environment.
  • Green LED is used focusing and aiming barcode.
  • Buzzer with different prompt sound effects for the different states.

The scanner module can also be configured tp supports adding custom prefix/suffix to the data, defining multi-national keyboard, data editing and many other functions.

The module communicates with the host through the TTL-232 (UART) for communication. So it can be used easily with any host offering UART support for data transmission.

Using it with Arduino or UIFlow programming is a charm, you can send the scanned data to the receiver for processing via wired or wireless connection through M5Atom Lite.

Great to create shop article scanner, Barcode/QR-Code scanner, inventory scanner.
