## Description

  The SparkFun Qwiic 5V Boost simplifies interfacing 5V I2C devices with the 3.3V Qwiic ecosystem. It takes the 3.3V I2C signals and power from its Qwiic connectors and boosts them to 5V, available on the PTH pins. This is perfect for powering peripherals like RGB LEDs or DC fans commonly used in SPS30, SEN54, and SEN55 air quality and particulate matter sensors. To make this board more compatible with our Qwiic ecosystem, it features 3V3/5V jumpers that allow you to independently set the logic levels of the I2C signals on the PTH pins. This enables connection to I2C devices that require either 3.3V or 5V for their power and communication needs. Furthermore, the TTL-based logic-level shifting mechanism can also be applied to other communication interfaces, such as serial buses, mirroring the capability of our SparkFun Single Supply Logic Level Converter. This product features Qwiic Connectors.
