Gravity: Ring 2D QR Code Scanner Module

SKU: SEN0486

This highly integrated QR code scanner with excellent performance can recognize common 1D codes and 2D codes. With a small size, it employs easy-to-connect Gravity Interface and is equipped with a RGB indicator that feeds back the sensor recognition status by showing different colors. Operating at 3.3V/5V, the scanner is compatible with UART and I2C communication, which makes it easier to develop on controllers like Arduino, ESP32, Raspberry Pi, etc. It can be used in self-service vending machines, subway gates, access control, payment machines, etc.
