Atomic QRCode2 Base
Description
Atomic QRCode2 Base is specifically designed for the ATOM series hosts. It is a 1D/2D barcode scanning base that supports 3 major types of 2D barcodes and 8 types of 1D barcodes. The base features a built-in buzzer and supplementary LED light, providing sound effects in different states, and a red LED for focus and aiming assistance. The module uses TTL communication, making it easy to transmit data via a serial port. You can use the ESP32 built into the M5Atom host to transmit scanned data to the receiving end via wired or wireless means. The back of the base is equipped with magnets, M3 screw holes, and LEGO-compatible holes, offering various mounting options. It is suitable for logistics, retail, manufacturing, and other fields.
