Espressif Systems has introduced the ESP32-PICO-V3-ZERO-DevKit, a new development kit that delivers out-of-box connectivity to ACK Cloud services along with features such as Alexa voice control, Frustration-Free Setup, and Amazon Dash Replenishment for connected devices. The new development kit is built around the ESP32-PICO-V3 System-in-Package and offers 2.4GHZ Wi-Fi and Bluetooth –Low-Energy coexistence in a small footprint of 16 x 23 x 2.3 mm.

The device has a PCB antenna and a 4 MB SPI flash, while at the core of the ESP32-PICO-V3-ZERO(ACK) module is the ESP32-V3 SoC, which has an Xtensa dual-core 32-bit LX6 microprocessor designed with TSMC’s 40 nm low-power technology. Apart from this, the ESP32-V3 SoC features a crystal oscillator, filter capacitors, and an RF matching network.

The ESP32-PICO-V3-ZERO-DevKit fully supports Amazon's Alexa Connect Kit (ACK), a managed service that makes it easy for device manufacturers to build products that connect quickly and easily to Amazon services at a fixed per-device cost. The default firmware of the ESP32-PICO-V3-ZERO-DevKit allows the customers to easily connect to their devices to Alexa and the Internet.
