The Power Supply kit is a handy device that can be used in a multitude of projects. You can use it to wirelessly power your builder base and all connected components. The power supply accepts 7-12V batteries via a 2.1mm barrel jack and regulates the voltage down to 5V. The power supply is connected to the 5V and GND ports on the builder base.
Step 1: PCB Assembly and Soldering
Download the Power Supply Kit Bill of Materials:
Gather your Power Supply Kit PCB and all required components listed in the BOM.
It is especially important to follow the BOM exactingly as it tells you where to place the components on the PCB. The fifth column on the BOM is the “parts” column. This column designates which position on the PCB you need to place each component. For example, if under the parts column you have a resistor labeled r1 you would then find the position marked r1 on the PCB and place the resistor there.
Using some form of work holder is advised. You can find a list of suitable work holders on our Recommended Tools List.
Step 2: Connecting to the Builder Base
You have two options for connecting the power supply to your Builder Base: you can use the male headers on the bottom of your PCB to stick it on the GND and VCC rails of a bread board, or you can use the jumper terminals located on the top of your power supply. Both options serve the same purpose, but one might work better for a given project than the other
