Espressif Systems has launched a new wireless compact size, high-performance module named ESP32-PICO-V3-ZERO that promises to provide seamless connectivity with ACK cloud services. Alexa Connect Kit (ACK) is the other name of this module that comes with Espressif. It is a small-footprint (16 x 23 x 2.3 mm) module that is based on ESP32-PICO-V3, a System-in-Package (SiP) device integrating the ESP32-V3 SoC, a 4 MB SPI flash, a crystal oscillator, filter capacitors, and RF matching links. This integration reduces the complexity of the supply chain and improves control efficiency with assembly and testing done at the SiP level.
The module is pre-certified for regulatory certifications such as FCC, CE, SRRC, IC, and RCM. It enables customers to build and manage connected devices with ease. At the core of the module is an Xtensa dual-core 32-bit LX6 microprocessor with integrated 2.4 GHz Wi-Fi, Bluetooth, and Bluetooth Low Energy connectivity. This SoC is designed with TSMC’s 40 nm low-power technology.
The module provides full support for Amazon's Alexa Connect Kit (ACK) which is a managed service to enable manufacturers to develop products that connect quickly and easily to Amazon services (all at a fixed per-device cost). This does not require managing cloud service, writing an Alexa Skill, or developing complex firmware/companion phone applications. The module helps users to create products that can be widely used in the field of smart homes in an easy, quick, and cost-effective manner.
