Espressif Systems ESP32-PICO-V3-ZERO Alexa Connect Kit (ACK) Module

Espressif Systems ESP32-PICO-V3-ZERO Alexa Connect Kit (ACK) Module is based on the ESP32-PICO-V3 System-in-Package (SiP) device. The kit provides a complete Wi-Fi and Bluetooth® solution with an embedded Xtensa® dual-core 32-bit LX6microprocessor. The module has a 4MB SPI flash, and an ESP32 chip, which is a single 2.4GHz Wi-Fi and Bluetooth combo chip. The ESP32-PICO-V3-ZERO integrates all peripheral components seamlessly. It includes crystal oscillator, flash, filter capacitors, and RF matching links in one single package. Module assembly and testing are already done at the SiP level. The ESP32-PICO-V3-ZERO reduces the complexity of the supply chain and improves control efficiency. It is ultra-small in size, with robust performance and low energy consumption.
