Frequency Control Components for Wearable Projects

Tiny, intelligent, and beautiful.
Our recommendations for the intricate world of wearables

Wearable projects present unique challenges: demanding the smallest, lowest power consumption and best value parts.

All of the components within our wearables collection have been specially chosen for their combination of tiny form-factor, low power consumption and competitive price to make choosing these parts easy.

 

More space for your board and your budget with our specially chosen wearables-recommended parts.

 

Find the Golledge wearables component collection within our CADSoft Eagle Part Library

 

To make life a little easier for the design engineer we’ve put together a library of parts we specially recommend for new designs. Within the Golledge part library you can find schematics, package drawings and further product details to help with designing-in Golledge components. All of our wearables parts are available within the library, along with other industry favourites from our product range.
