ATOM QR-CODE is an M5Atom compatible module for reading Barcode/QR-codes. The product includes two parts: an M5Atom Lite unit and code scanning module. It supports 6 kinds of 2D codes and 19 kinds of 1D codes. It has 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 5mil. 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 has different prompt sound effects in different states. The module also supports adding custom prefix/suffix to the data, defining multi-national keyboard, data editing and many other functions, it uses TTL for communication, and can easily use serial port for data transmission. It can be easily used in Arduino or UIFlow programming,You can send the scanned data to the receiver for processing via wired or wireless connection through M5Atom Lite.

The scan module has been configured at the factory. M5Atom Lite has no pre-burn preset program.You need to burn the following example program for use. If you need to change the configuration, please refer to the user manual to scan the QR code for configuration. If you restore the factory settings, please scan to confirm that you are in TTL communication mode,and the baud rate setting is correct.The reading of some 1D code or 2D code needs to be enabled by scanning qr-code of user manual to configure.
EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification.
