# Kinetis K66 SDK

Go to the MCUXpresso SDK Builder linked below. If you **click on "Select Development Board"** you will be taken to a page where you can select the Kinetis K66 microcontroller and put together an SDK package. You might need to **login** again to your NXP account.

## REAL TUTORIAL

Open the MCUXpresso program you just installed. First choose which directory you want your workspace to be. After that you will be greeted with the welcome page. There click on the "Download and Install SDK".

Once you clicked, another tab opens. This page might take a while to open fully. As you can see on the bottom right of the page there is a percentage counter refreshing the SDK repositories. Wait for it to finish then the list of SDKs will show up.

### SDK examples

Now you can start by running a Hello World program in your board. First things first is to import an SDK example. Then we can figure out how to run code on our board. Go to File > New > Import SDK example(s).
