The ATOM QR-CODE is an M5Atom-compatible module for reading barcodes/QR codes. This includes two parts, an M5Atom Lite unit and a code-scanning module. It supports 6 kinds of 2D codes and 19 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 5mil. It also has a variety of reading modes, which can be adjusted to automatic continuous trigger or manual trigger as required. It has its own buzzer, which has different prompt sound effects in different states. The module also supports adding custom prefixes/suffixes to the data, defining multi-national keyboards, data editing and many other functions. It uses TTL-232 for communication, and can easily use serial ports for data transmission. It can be easily used in Arduino or UIFlow programming, and you can send the scanned data to the receiver for processing via a wired or wireless connection through M5Atom Lite.
