This code scanner is designed specifically for the ATOM series hosts. The 1D/2D barcode scanning base supports 3 major types of 2D barcodes and 8 types of 1D barcodes. It has a built-in buzzer and supplementary LED light, providing audio feedback in different states, and a green LED for focus and aiming assistance. Scanned data can be transmitted to the receiving end via wired or wireless means using the ESP32 built into the M5Atom host. The base includes magnets, M3 screw holes, and LEGO-compatible holes on the back, offering multiple mounting options. It is ideal for use in logistics, retail, manufacturing, and other fields.
