Overview
ESP32-PICO-V3-ZERO is an Alexa Connect Kit (ACK) module with Espressif. 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.
Hardware
ESP32-PICO-V3-ZERO
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 Espressif’s popular 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.
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.
