Wireling Adapter TinyShield


Regular price $ 9.95 Save $ -9.95

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 to your project with ease! 

Up to 8 Wireling Adapters may be stacked together by changing the address resistors on the board. I/O Pin 4 is used to control power to the Wireling Adapter. Driving it high will activate the Adapter board and its sensors, while driving it low will power down the board and its sensors to save on power consumption! Using a multiplexer also allows you to use two or more I²C devices with the same address, without interference problems.

*NOTE: 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.
