This Pi Hat allows users to add Wirelings to their Pi projects. Featuring a 4-channel Multiplexer, Real-Time Clock (RTC), on-board voltage regulation and level shifting, this board allows you to add up to 4 Wireling Boards to your project with ease! 

There are two options when ordering this board:

1. Soldered: The female header pins to attach the Pi Hat to a Pi are soldered so you can get building as soon as possible

2. Not-Soldered: This option is best for you when you already have soldering equipment at home, or you want to use some other form of header pins
