Add an SD slot and prototyping area in a single shield.
The Arduino MKR SD Proto Shield allows you to easily connect a MicroSD card to your MKR form factor board. Use it to enhance the IoT features of your MKR1000, as well as store data coming from the web or sensors read by your board!
There's also a small prototyping area for soldering components.
