Use an Alexa Connect Kit (ACK) development kit to build a device prototype and test your product.

What's the ACK development kit?

The ACK development kit provides a starting point for you to build an ACK-based device prototype quickly. A development kit typically contains the following items:

An ACK development shield board with an integrated ACK module.
A barcode that you use to register your device with Alexa.
All the necessary cords and adapters to power the device.
Might contain a HMCU development kit.

For more details about the components that power ACK-based devices, see ACK Component Descriptions.

Purchase the ACK development kit

There are two ACK development kits available for purchase, the Espressif development kit and the USI development kit. These kits are generally available worldwide. However stock might vary by region.

Note: The ACK getting started tutorials use an Arduino Zero development board as it's host microcontroller unit (HMCU). To complete these tutorials, use an Arduino Zero development board with your development kit. You might have to purchase the Arduino Zero separately, depending on the development kit you use.

Espressif development kit

The full name of the Espressif development kit is the ESP32-PICO-V3-ZERO-DevKit. To find a kit in your region, use the following links.

Important: The Espressif development kit doesn't come with an HMCU development board. You must purchase this board separately. For example, to represent your HMCU, you can use an Arduino Zero board or another supported development board.

Purchase other HMCUs that work with ACK

If you purchase an Espressif development kit, you must also purchase an HMCU separately, such as an Arduino Zero or another supported development board. If you use the USI development kit, you don't need to purchase a separate HMCU.

Arduino Zero development board

Use the following links to purchase the Arduino Zero development board.

Other HMCU development boards

You can also prototype and build ACK-based devices on other commercially available HMCUs instead of the Arduino Zero. For an updated list of additional HMCUs that you can use, see ACK HMCU Development Kits.
