Gravity: Ring 2D QR Code Scanner Category_Electronics/Connectors The open drain setup allows

The open drain setup allows multiple motion sensors to be connected on a single input pin

The SparkFun Line Follower Array requires 5V of power with a supply current range of 25-185mA with strobing disabled and 16-160mA with it enabled

1 x Diffused LED - Red 10mm

Complete receiver in 10mm x 10mm x 1

these switching regulators have an efficiency of 85% to 95% for most combinations of input voltage and load

Gravity: Ring 2D QR Code Scanner Category_Electronics/Connectors The open drain setup allowsThis 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 colorful 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,
