The SparkFun Single Supply Logic Level Converter combines a boost converter (TPS61200), adjustable voltage regulator (MIC5205), and logic level translator (TXB0104) into one board. It provides 5V to the high side of the TXB0104 and the low side is programmable to 3.3V, 2.5V and 1.8V.
This little board has a bi-directional voltage-level translator with automatic direction sensing. You will be able to use your 5V or 3.3V logic microcontroller with 3.3V or 5V sensors. What makes this converter truly special is the fact that you can supply it with 3.3V and it will create the 5V to power your sensor or other board up to 600 mA.
