Espressif Systems has very recently introduced the ESP32-S3-BOX AI voice devkit designed for the development of applications with offline and online voice assistants, and whose design I find similar to the M5Stack Core2 devkit, but the applications will be different.
The ESP32-S3-BOX features the latest ESP32-S3 processor with WiFi and BLE connectivity, AI capabilities, as well as a 2.4-inch capacitive touchscreen display, a 2-mic microphone array, a speaker, and I/O connectors with everything housed in a plastic enclosure with a stand.
- WiSoC – ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with Wi-Fi & Bluetooth 5, AI instructions, 512KB SRAM
- Memory and Storage – 8MB octal PSRAM and 16MB QSPI flash
- Display – 2.4-inch capacitive touchscreen display with 320×240 resolution
- Audio – Dual microphone, speaker
- USB – 1x USB Type-C port for power and debugging (JTAG/serial)
- Expansion – 2x Pmod-compatible headers for up to 16x GPIOs
- Power LED, Mute button and LED, boot mode button, reset button
- 6-axis IMU Sensor (IvenSense ICM-42670)
- Infrared “controller”
- Power Supply – 5V via USB Type-C connector or dock
- Dimensions – TBD
Software support for ESP-S3-BOX built upon 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 the LVGL open-source graphics library used to develop HMI solution. You’ll find the ESP-BOX AIoT development framework and documentation to get started with the AI voice development kit on Github.
ESP32-S3-BOX AI voice development kit can be pre-order for $45 on Amazon, Aliexpress and Adafruit. At the time of writing, the devkit is only in stock on Aliexpress, and interestingly it’s the just-opened official Espressif Systems store on Aliexpress, so we may expect the company to sell future devkits that way going forward.
