Step 1: Learn about the Development Kit Components
Use this documentation to learn about your development kit and start setting it up. Use the documentation that for the type of development kit that you purchased; the Espressif development kit or the USI development kit.
If you don't have a development kit yet, see Obtain the ACK Development Kit.
Espressif development kit
The Espressif development kit for Alexa Connect Kit (ACK) comes with a development board fitted with an integrated ACK module. In the following sections, you learn what's in the box, and get an overview of the development board components.
What's in the box
The following are the items included in the Espressif development kit box:
- A development board fitted with an integrated ACK module.
- A barcode that you use to register your device.
The getting started guide uses an Arduino Zero development board to represent an HMCU (Host Microcontroller Unit). If your ACK development kit doesn't come with an Arduino Zero development board, and you want to complete the getting started examples, purchase an Arduino Zero development board.
To complete the getting started guide, you'll also need the following components not included in the Espressif development kit:
- An LED with internal resistor to prototype a smart light device.
- A micro-USB cable.
- If your computer has only USB Type-C ports, you need a USB Type-C to USB 3.1 female adaptor cable.
Espressif development board components
The following table lists the development board components and their location on the board, illustrated following.
| Label | Component | Description |
|---|---|---|
| A | Debug port | A micro-USB port used to connect the development board to your computer in order to debug, provision, and update the module firmware. |
| B, C | Pass-through headers | Use the pass-through headers to connect hardware peripherals, such as an LED or a fan. The header pins connect the development board to the Arduino Zero, and are pass-through connections. |
| D | ACK module | The ACK module is the central component of the development board, and connects to the device's HMCU and to Alexa and ACK managed services. |
| E | Power LED | Red if the module has power. |
| F | Status LED | Indicates the status of the device: Green — The ACK module is connected to Wi-Fi and the device is registered with the ACK managed service. White — The ACK module has power and the device is product provisioned, but the device isn't registered with the ACK service. Red — The ACK module is in the module provisioned state or there is an error. |
| G | Reset button | Resets the ACK module. Can also reset the Arduino Zero if it is connected. |
| H | Development board jumpers | The development board comes with jumper caps on the TX, RX, INT_B, and RES_B connectors. When a jumper cap is in place, the signal is routed to the board pin headers. |
| I | Device Serial Number (DSN) | Each development board has a unique DSN. The DSN is used to register and identify your device with Alexa and ACK managed services. |
USI development kit
The USI development kit for Alexa Connect Kit (ACK) comes with a development board fitted with an integrated ACK module with MediaTek chipset, an Arduino Zero, and other items. In the following sections, you learn what's in the box, and get an overview of the development board and Arduino Zero hardware components.
What's in the box
The following table lists the items included in the USI development kit box, illustrated following.
| Label | Description |
|---|---|
| 1 | A USI MT7697H Development Board with integrated ACK Module. |
| 2 | An Arduino Zero development board. |
| 3 | A USB Type-C to USB 3.1 female adaptor cable. |
| 4 | A Micro-USB cable. |
| 5 | An LED with internal resistor that you use to prototype a smart light device. |
| — | A barcode that you use to register your device. |
USI development board components

Arduino Zero board components
The following table lists the Arduino Zero board components and their location on the board, illustrated following.
| Label | Component | Description |
|---|---|---|
| A | Reset button | Resets the Arduino Zero. |
| B, C | Pin headers | Pass-through connectors to the ACK Development Board used to connect the two boards. |
| D | Status LED | For details about the Arduino Zero status LED, see the Arduino Zero documentation. |
| E | Programming Port | Provides power to the development board, and is used to program and debug the Arduino Zero. |
| F | Native USB Port | You don't use this port. |
