Summary of ESPRESSIF TEAMS UP WITH AMAZON ΤO INTRODUCE THE ESP32-PICO-V3-ZERO ALEXA CONNECT KIT
The ESP32-PICO-V3-ZERO is Espressif’s Alexa Connect Kit (ACK) module that simplifies building Alexa-compatible devices. It’s a tiny 16 x 23 x 2.3 mm SiP based on ESP32-V3, includes 4 MB SPI flash, crystal oscillator, filter caps, RF matching, and a PCB antenna. It provides 2.4 GHz Wi‑Fi and Bluetooth/BLE, connects to a host MCU via UART, and ships with pre-programmed, Amazon-managed ACK firmware and credentials for out-of-box Alexa features like Frustration-Free Setup and Dash Replenishment.
Parts used in the ESP32-PICO-V3-ZERO:
- ESP32-PICO-V3 SiP (based on ESP32-V3 SoC)
- 4 MB SPI flash
- Crystal oscillator
- Filter capacitors
- RF matching links
- PCB antenna
- ACK module firmware (pre-programmed)
- UART interface to host MCU
Over the past few years, we have seen companies unveil their Alexa Connect Kit (ACK) for smart homes, like the STM32GO71. However, ESpressif has announced its forthcoming Alexa Connect Kit (ACK) module known as ESP32-PICO-V3-ZERO.
The ESP32-PICO-V3-ZERO enables an easy way for customers to create Alexa-compatible devices. With Alexa Connect Kit (ACK) you can quickly and easily build products your customers will love, all at a fixed per-device cost. For your customers, products built with ACK include Alexa control through voice and mobile applications, Amazon’s Wi-Fi Simple Setup, and Amazon Dash Replenishment Service (optional). For developers, ACK enables you to connect your devices to Alexa without worrying about managing cloud services, writing an Alexa Skill, or developing complex networking and security firmware.
ESP32-PICO-V3-ZERO has a small form factor, measuring at just 16 x 23 x 2.3 mm, and based on the ESP32-PICO-V3 SiP. The SiP is based on the ESP32-V3 SoC, with a 4 MB SPI flash, a crystal oscillator, filter capacitors, and RF matching links. It offers 2.4 GHz 802.11 b/g/n, Bluetooth and Bluetooth Low Energy connectivity (BLE) to the host MCU. It is also equipped with a PCB antenna, with the host MCU being able to be connected to the ESP32-PICO-V3-ZERO module via a UART interface.
For software features, the ESP32-PICO-V3-ZERO features a pre-programmed ACK module firmware. It is also pre-configured to have credentials and connect to an ACK-managed cloud service. The ACK module firmware is managed by Amazon and enables 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.
