The ESP32-PICO-V3-ZERO is a module that is based on ESP32-PICO-V3, a System-in-Package (SiP) device. It provides complete Wi-Fi and Bluetooth functionalities with embedded Xtensa dual-core 32-bit LX6 microprocessor. The module integrates a 4 MB SPI flash. At the core of this module is the ESP32 chip, which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC’s 40 nm low-power technology. ESP32-PICO-V3-ZERO integrates all peripheral components seamlessly, including a crystal oscillator, flash, filter capacitors and RF matching links in one single package. Module assembly and testing are already done at SiP level. As such, ESP32-PICO-V3-ZERO reduces the complexity of supply chain and improves control efficiency. It is ultra-small in size, with robust performance and low energy consumption.
ESP32-PICO-V3-ZERO is a module for Alexa Connect Kit (ACK), a managed service that makes it easy to integrate Alexa into your products. With ESP32-PICO-V3-ZERO and its default firmware, you can connect your devices or system to Alexa and the Internet without worrying about managing cloud services, writing an Alexa Skill, or developing complex networking and security firmware. If you add ESP32-PICO-V3-ZERO to your device,
you can easily, quickly and economically create products that customers love.
