Description
This board is perfect for those looking to use the Qwiic/Stemma QT standard in their next project while also utilizing a sensor or device that requires 5V power or logic. It allows you to use the 3V power and logic from your Raspberry Pi or ARM Cortex microcontroller, and boosts/shifts it up to 5V to work with older or high-power devices that may not be compatible with only 3V. On one side, there are 3V power and logic level inputs. The middle of the board features a 5V charge-pump boosting regulator that can provide 100mA continuous (250mA peak) and level shifting circuitry. On the other side, the same I2C traffic is safely shifted up to 5V. Additionally, for those using a board that requires 5V power but 3V logic I2C, there is a solder jumper on the back that can be cut/soldered to set the output logic level to unshifted 3V.
