Espressif has announced the impending launch of an ESP32-powered Alexa Connect Kit (ACK) in module form, measuring just 16x23x2.3mm (around 0.63x0.91x0.09") including on-board antenna.
"ESP32-PICO-V3-ZERO is an Alexa Connect Kit (ACK) module with Espressif," the company explains of its design. "It provides an easy way for customers to build Alexa-compatible devices without worrying about managing cloud services, writing an Alexa Skill, phone applications or complex device firmware. It provides Alexa connectivity and supports features like Frustration-Free Setup and Amazon Dash Replenishment."
The module itself, measuring a compact 16x23x2.3mm (around 0.63x0.91x0.09" with an on-board PCB antenna and connectivity for an external antenna, it built around Espressif's ESP32-PICO-V3 system-in-package (SiP) — itself containing the ESP32-V3 system-on-chip, which includes 4MB of SPI flash memory, a 2.4GHz 802.11b/g/n Wi-Fi radio, and both Bluetooth and Bluetooth Low Energy (BLE) connectivity.
"ESP32-PICO-V3-ZERO comes pre-programmed with the ACK module firmware," Espressif continues. "It is also pre-provisioned to have credentials and connect to an ACK-managed cloud service. The ACK module firmware is managed by Amazon and provides out-of-box features such as Frustration-Free Setup, Alexa connectivity and Amazon Dash Replenishment."
"Customers can implement interfacing with peripherals on the host MCU when it is connected to the ACK module over a UART interface. This architecture significantly reduces software development and maintenance complexity for customers, while also providing a rich set of product features."
Espressif has not yet share pricing for the module, but has published technical details on the official product page.
