Adafruit QT 3V to 5V Level Booster Breakout - STEMMA QT / Qwiic

If you're utilizing the Qwiic or Stemma QT standard but require 5V power or logic, this board is the solution you need. It adeptly transforms 3V power and logic from a Raspberry Pi or ARM Cortex microcontroller to 5V, accommodating devices like the Sensirion SEN54 with its 5V requirements.

Featuring a compact 5V charge-pump boosting regulator, the board provides 100mA continuous and peaks at 250mA. The level shifting circuitry ensures I2C traffic is shifted from 3V to 5V safely. For projects requiring 5V power with 3V logic I2C, a solder jumper allows easy modification to maintain 3V logic levels.

Designed for simplicity, this adapter includes breadboard breakout pins and functions as a QT-to-perfboard adapter. The STEMMA QT connectors offer seamless connectivity with I2C connectors, supporting solderless links to various sensors and accessories with the right cable.
