The Meadow.Foundation peripherals library is an open source repository of drivers for various peripherals such as sensors, motors, displays, cameras, and other peripherals which make it easy to add hardware to your Meadow application.

The peripherals are split into two groups; the first group is general, core peripherals that are included in the main Meadow.Foundation NuGet package. The second group are additional drivers that are available via separate NuGet packages to keep the core size to a minimum.
