Description
Adafruit QT 5V to 3V Shifter Breakout has 5V-safe power and logic input on one side. In the middle is a 3.3V regulator that can provide 500mA plus level shifting circuitry. On the opposite side is the same I2C traffic but now safely shifted down to 3.3V to allow usage with the vast number of sensors and devices that are not 5V safe.
