M5Stack ATOM 2D/1D Barcode Scanner Kit

Atom QR-code is an M5Atom compatible module for reading barcode and QR codes. The product includes two parts: an M5Atom Lite unit and a code scanning module. It supports six kinds of 2D codes and nineteen kinds of 1D codes. It has a built-in lighting LED, which can easily identify codes even in a dark environment. The green LED is convenient for focusing and aiming. The effective recognition accuracy of high-resolution CMOS imaging reaches 5 mil. In addition, it has a variety of reading modes, which can be adjusted to automatic continuous trigger or manual trigger as required. The module has its own buzzer, which produces different prompt sound effects in different states. The module also supports adding custom prefix and suffix to the data, defining multi-national keyboard, data editing, and many other functions. It uses TTL-232 for communication and can easily use a serial port for data transmission. It can be easily used in Arduino or UIFlow programming, allowing you to send the scanned data to the receiver for processing via wired or wireless connection through M5Atom Lite.
