Required hardware

You need the following hardware to finish the basic steps in the tutorial.

  • Raspberry Pi - Use a Raspberry Pi 3 or 4.
  • Micro SD card - Minimum 8 GB.
  • USB 2.0 microphone - Raspberry Pi doesn't have a built-in microphone. To interact with Alexa you must plug in an external microphone.
  • External speaker or headset - Your audio source needs to connect to the Pi with 3.5 mm audio cable.
  • USB keyboard and mouse - Choose any compatible keyboard and mouse.
  • Raspberry Pi fan - Choose any compatible fan. Without a fan, the Raspberry Pi might overheat.
  • HDMI monitor - Choose any compatible monitor. Alternatively, you can remote SSH into your Pi.
  • Internet connection - Ethernet connection or a 2.4 Ghz Wi-Fi.

Required software

  • Raspbian Operating System – Use Raspbian Buster. The instructions in this tutorial use NOOBS to download the latest version of Raspbian for you.
  • The latest version of the AVS Device SDK – The instructions in this tutorial download the latest version of the SDK that's available.

Advanced tutorials

Required hardware

For the Advanced Pi LED tutorial, you need some additional hardware. You can use any breadboard or LEDs you might have. This tutorial uses the GPIO Breakout Board Bundle from Canakit.

For these tutorials, we've selected an inexpensive USB microphone, which isn't optimal capturing far field audio. When you ship a commercial product, consider leveraging the Development Kits for AVS. These kits provide complete, end-to-end system reference designs for creating products for Alexa.
