ESP32-PICO-V3-ZERO, the Alexa Connect Kit (ACK) module with an Espressif chipset, and its related development kit ESP32-PICO-V3-ZERO-DevKit provide an easy way for customers to build Alexa-connected devices without worrying about managing cloud services, writing an Alexa Skill, phone applications or complex device firmware. They provide Alexa connectivity and support features like Frustration-Free Setup and Amazon Dash Replenishment.
ACK Module
ESP32-PICO-V3-ZERO is a small footprint (16 x 23 x 2.3 mm) module based on the ESP32-PICO-V3 SiP. This SiP is based on the ESP32-V3 SoC, with a 4 MB SPI flash, a crystal oscillator, filter capacitors and RF matching links. It provides 2.4 GHz 802.11 b/g/n, Bluetooth and Bluetooth Low Energy connectivity to the host MCU. It comes with a PCB antenna. The host MCU can be connected to the ESP32-PICO-V3-ZERO module through a UART interface.
At the core of this module is ESP32-V3 SoC, which is an XTensa LX6 dual-core 32-bit microcontroller with integrated Wi-Fi and Bluetooth connectivity. This SoC is designed with TSMC’s 40-nm low power technology.
The module comes pre-certified for regulatory certifications such as FCC, CE, SRRC, IC and RCM.
ACK Development Kit
ESP32-PICO-V3-ZERO-DevKit is based on the ESP32-PICO-V3-ZERO (ACK) module. With its compact size, high performance and seamless connectivity, ESP32-PICO-V3-ZERO-DevKit aims to become the solution of choice for makers who wish to build Alexa-connected devices. The pin layout of ESP32-PICO-V3-ZERO-DevKit is compatible with that of the Arduino Zero development board and, therefore, it can be directly plugged into the Arduino Zero board, or get easily connected to other host boards and peripherals.
Software
ESP32-PICO-V3-ZERO comes pre-programmed with the ACK module firmware. 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.
