[elecena] Gravity: Ring 2D QR Code Scanner - zmiany ceny This highly integrated QR code scanner can recognise common 1D codes and 2D codes. With its compact footprint, it employs the easy-to-connect DFRobot Gravity Interface and is equipped with a colourful indicator that feeds back the sensor recognition status by showing different colours. 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 and more. It can be used in self-service vending machines, subway gates, access control, payment machines and other similar scenarios. The product wiki is on hand to help you get started.
