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.

Note :

You can also use this TinyShield without the TinyDuino – modifying the connecting cable by removing the opposite connector and stripping/tinning the wires, you can solder the connector cable to any other microcontroller board of your choice!
When bringing the device out of low power mode, it may be necessary to re-initialize certain sensors. Check the component datasheets to ensure proper operation and setup times for each Wireling is used.

The Wireling Adapter TinyShield (ASD2022) incorporates level shifting and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.
