This is a straightforward, simple, easy-to-use, and reliable boost converter that provides stable 5V DC output with currents of 1A or more using a standard 3.7V LiPoly/LiIon battery. It uses the TI TPS61090 boost converter which has great specs, including:
A standard JST connector is provided for the battery input, and a JST SH connector with 1mm pin spacing is provided for power output. Also included is a 6" cable with mating JST SH plug to connect to the output, with bare wire on the other end.
Note that this product does not include a battery charger-- this is just the boost converter that steps the battery voltage up from 3.7V to 5V.
Also note that this product does not include reverse input polarity protection, so you will need to make sure your battery has the correct polarity. Polarity is indicated on the PCB at the input connector, and matches the standard polarity used by Adafruit and Sparkfun LiPo batteries. You can read more about batteries and chargers we have tested with this supply on our User Forum.

At Brickstuff, we’re passionate about all the great things you create, and we want to help bring those awesome creations to life! We’ve worked hard to develop an ever-expanding line of modular lighting and automation products for your model buildings, train and city layouts, and custom creations. Just about anything you build, you can bring to life using our products.
Simplicity and flexibility are at the heart of everything we do. We've engineered our light modules so you can install them anywhere, and have them up and running in minutes. You can connect the modules end-to-end to create larger installations, and you can connect Lighting Effect Modules to your lighting setup to bring your creations to life. Realistic lighting effects-- such as a flickering fireplace or lights inside a model house that turn on and off automatically-- can be easily implemented. You don't need to worry about the electronics-- just connect your lights, attach a power source, and get ready to answer the question, "How'd you do that?"
