## AI overview

Espressif's October 2021 newsletter highlights Amazon's Alexa Connect Kit SDK, an ACK SDK-compatible development kit for Espressif hardware, ESP32-H2 certifications, cloud-connected IoT platform support, and NuttX and Zephyr support on ESP32 SoCs.

## Source excerpt

Hi everyone, Last week Amazon announced Alexa Connect Kit SDK (ACK SDK) , a software package that enables Original Design Manufacturers (ODMs) and System Integrators (SIs) to build their own ACK-based modules and differentiated, Alexa-compatible, smart-device solutions without having to worry about managing cloud services, building an app, or writing an Alexa skill.
