Wireling Arduino Shield


Regular price $ 19.95 Save $ -19.95


This Arduino Shield allows users to add Wirelings to their Standard Arduino 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 male header pins to attach the Arduino Shield to an Arduino 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. (The header pins in the product images will ship with this option)

Note* 5-Pin Wireling cables not included and sold separately.
