ESP32-S3-BOX specificationsThe company claims that the ESP32-S3-BOX is ideal for the development of smart speakers, gateways, and IoT devices that require human-computer voice interaction. The development kit supports remote voice interaction through the built-in microphone array, offline voice wake-up and voice command recognition in Chinese and English, reconfigurable voice commands again in Chinese and English, as well as to ESP-RainMaker IoT development framework.

Software support for ESP-S3-BOX based on previous work done for ESP32, including ESP-Skainet Voice Assistant and ESP-DL Library for Machine Learning, as well as third-party solutions like Alexa for IoT SDK or Graphics Library open source LVGL used to develop an HMI solution. You will find the ESP-BOX AIoT development framework and documentation to get started with the AI ​​voice development kit on Github.

ESP32-S3-BOX Bluetooth 5G 4G LTEA blog post goes into more detail on the current and future capabilities of the kit, including the use of Pmod connectors to add Zigbee and Thread connectivity with an ESP32-H2 module and / or even cellular IoT connectivity (5G, NB-IoT, LTE Cat-M1).

ESP32-S3-BOX AI Voice Development Kit can be pre-ordered for $ 45 on Amazon, Aliexpress and Adafruit. At the time of writing this article, the devkit is only in stock on Aliexpress, and it is interesting that it is the official Espressif Systems store that just opened on Aliexpress, so we can expect that. that the company sell future devkits this way in the future.
