Single Supply Logic Level Converter Hookup Guide

LightningHawk Introduction
The 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. The default low side voltage is 3.3V. With this device you can use your 5V microcontroller with 3.3V sensors and vice versa without the need for a second power supply!
What makes this logic level converter truly special is the fact that you can supply it with 3.3V and it will boost it to 5V - meaning you can use your 3.3V system, and convert directly to another 5V sensor - and even power your sensor or other board! We will use a 3.3V microcontroller and a 5V sensor for the example. However, you can use still this board with a 5V microcontroller and a 3.3V sensor.
Required Materials
To follow along with this project tutorial, you will need the following materials to level shift between a 3.3V microcontroller with a 5V sensor. You may not need everything, depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
Tools
You will need a soldering iron, solder, and general soldering accessories.
