This TinyShield is the heart of the Wireling line. Featuring a 4-channel Multiplexer, on-board voltage regulation, and level shifting - this board allows you to add up to 4 Wirelings per Shield to your project with ease! Using a multiplexer also allows you to use two or more I²C devices with the same address, without interference problems.

Up to 8 Wireling Adapters may be stacked together by changing the address resistors on the board for a total of 32 Wirelings. 

Wireling Adapter TinyShields are compatible with TinyCircuits processors that have a 32-Pin Connector.
