Adafruit 5V-to-3V Level Shifter Breakout for STEMMA QT and Qwiic

Description

If you’re looking to use the new Qwiic / Stemma QT standard with a classic 5V microcontroller like the Arduino UNO, the Adafruit QT 5V to 3V Level Shifter Breakout is designed for you! This breakout safely shifts the 5V I2C signals down to 3.3V, protecting your 3.3V sensors and devices from damage.

The breakout includes a 3.3V regulator capable of supplying 500mA, with level shifting circuitry to convert I2C traffic from 5V to 3.3V. It features breakout pins for breadboard usage and is compatible with STEMMA QT connectors for solderless connections and chaining with compatible sensors and accessories.

• Supports 5V input on one side and outputs 3.3V I2C signals on the other side
• Includes 3.3V regulator providing 500mA current
• Compatible with STEMMA QT and Qwiic connectors for easy sensor interfacing
• Breadboard breakout pins included
• Compact size: 25.4mm x 18.0mm x 4.8mm
• Lightweight: 1.8g

Note: STEMMA QT cables are not included but are available separately.
