Atom QRCode is a scanning module kit capable of recognizing and reading 1D/2D barcodes. It includes an Atom-Lite host, supports 6 types of 2D codes and 19 types of 1D codes, and features built-in illumination LEDs for easy recognition even in dark environments. The green LED aids in focusing and aiming, while the high-resolution CMOS imaging ensures effective recognition accuracy of up to 5mil. The module offers multiple scanning modes, allowing you to switch between automatic continuous triggering and manual triggering as needed. It comes with a built-in buzzer that provides different sound prompts for various states. Additionally, the module supports adding custom prefixes and suffixes to data, defining multi-country keyboards, data editing, and many other functions. The module uses TTL for communication, making it easy to transmit data via a serial port. Whether you're using Arduino or UIFlow for programming, you can easily get started. You can use the ESP32 built into the Atom-Lite to send scanned data to a receiving end for processing, either wired or wirelessly.

The scanning module is pre-configured at the factory. The Atom-Lite does not come with built-in programs, so you need to flash the following example programs into the Atom-Lite. If you need to change the configuration, please refer to the user manual and scan the QR code for configuration. If you restore the factory settings, make sure to scan to confirm that you are in TTL communication mode and that the baud rate is set correctly. Some 1D and 2D codes require scanning a QR code to enable recognition.
