Customers say

Customers find the single board computer fun and easy to use for hobbies and tinkering. It recognizes their voice well and works perfectly using the sample code provided on the company’s website. However, some customers have experienced issues with power saving and wakeup words not working properly within 2 months. Opinions vary on the overall quality of the product.
【Easy to Use】: this voice recognition sensor is compatible with micro:bit, Arduino Uno and ESP32. It can be programmed using MakeCode and supports plug-and-play functionality. At the same time, this voice recognition sensor also support I2C and UART communication methods, with a Gravity interface.
【121 built-in fixed command words】: The offline voice recognition sensor comes with 121 built-in fixed command words, eliminating the need for users to record their own voices. For instance, in an intelligent window system, when it starts to rain or thunder, there’s no need for manual window operation. The offline voice recognition module can recognize the pre-set command word “close the window,” triggering the automatic closing of the window to cope with sudden weather changes.
【Self-Learning Function+Adding 17 Custom Command Words】: This voice recognition module is equipped with a self-learning function and supports the addition of 17 custom command words. Any sound could be trained as a command, such as whistling, snapping, or even cat meows, which brings great flexibility to interactive audio projects. For instance automatic pet feeder. When a cat emits a meow, the offline voice recognition module can recognize the meow and trigger the feeder to automatically provide food for the cat.
【No network required】: This voice recognition sensor can be used without the need for a network connection, making it suitable for various settings. It provides fast response to specific command words and instructions. Moreover, the onboard MCU is equipped with voice recognition algorithms, ensuring that conversations are not recorded or uploaded to the cloud, thus ensuring greater privacy and security.
【Integrated Microphone and Speaker with Compact Size】: built-in speaker and external speaker interface for real-time voice feedback of recognition results. Compact size of only 49×32 mm, convenient for embedding in applications.

ESP-WROOM-32 is a general-purpose WiFi-BT-BLE MCU module with powerful functions and a wide range of uses.

The core of this module is the ESP32 chip, which is scalable and adaptive.
The two CPU cores can be controlled or powered up independently.
The clock frequency can be adjusted from 80 MHz to 240 MHz.
The user can cut off the power to the CPU and use the low-power coprocessor to constantly monitor the state changes of peripherals or whether certain analog quantities exceed thresholds.
ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S, and I2C, etc.

ESP-WROOM-32 integrates traditional Bluetooth, low-energy Bluetooth, and Wi-Fi,

and has a wide range of uses: Wi-Fi supports a wide range of communication connections, and also supports direct connection to the Internet through a router;

while Bluetooth allows users to connect mobile phones Or broadcast BLE Beacon for easy signal detection.
The sleep current of the ESP32 chip is less than 5mA, making it suitable for battery-powered wearable electronics.

The ESP-WROOM-32 supports a data transfer rate up to 150 Mbps,

and after passing through the power amplifier, the output power can reach 22 dBm,

which can realize wireless communication in a wide range.

Therefore, this chip has leading technical specifications and has good performance in terms of high integration, wireless transmission distance, power consumption, and network connectivity.

The operating system of the ESP32 is freeRTOS with LWIP and also has built-in TLS 1.2 with hardware acceleration.
The chip also supports OTA encryption upgrade, and developers can continue to upgrade after the product is released.
