While we love our Raspberry Pi projects here at XDA, sometimes you don’t want the whole Pi; sometimes you just want a slice. Such is the case for people who purchase the individual microcontrollers you can find on the Raspberry Pi for their bespoke projects. And while the microcontrollers are a fantastic way to add a teeny-tiny brain to whatever you like, it doesn’t come with either a WiFi or Bluetooth adapter. Instead, you need to hook it up to an adapter yourself.
