Espressif ESP32-WROVER WiFi Modules for IoT Voice Applications

18.06.2019

The new ESP32-WROVER radio modules are the most feature rich radio solutions of all Espressif modules. Designed to create IoT devices with support for voice applications, ESP-WROVER, unlike other modules, has an additional 32 Mbit PSRAM chip on board. ESP32-WROVER modules implement WiFi 802.11 b/g/n and Bluetooth v4.2 BR/EDR/BLE protocols.

A powerful dual-core processor operates at frequencies from 80 to 240 MHz. A large amount of RAM allows you to process audio data in applications such as voice control, Internet radio, playback of compressed music content. Based on ESP32-WROVER, you can organize interaction with various cloud services, for example, Amazon Alexa, Google Assistant, and Baidu DuerOS

ESP32-WROVER modules differ in the size of the installed ESP32 chip and the antenna connection option. All modules are identical in terms of processing power and the number of peripherals on board.

Features of ESP32-WROVER modules:

Wi-Fi 802.11 b/g/n up to 150 Mbps.
Bluetooth classic BR/EDR + BLE v.4.1.
Interfaces UART, SPI, SDIO, I2C, SD card, I2S, ADC, DAC, GPIO, etc.
Protocols: IPv4, IPv6, SSL, TCP/UDP/HTTP/FTP/MQTT.
Operating supply voltage: 2,3 ... 3,6 V.
Average current consumption: 80 mA.
Operating temperature range: -40°C...85°C.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Data storage time in SSD increased thousands of times 14.07.2017

A group of Japanese scientists presented a development in the field of solid state drives. Researchers have shown that through data compression and changes in the writing method, it is possible to significantly increase the reliability of drives, compensating for the decrease in the number of write-erase cycles and increasing the storage time.

The essence of the development is a combination of two methods.

First, the controller compresses the data using the Huffman algorithm, which reduces the amount of data being written.

Second, frequently occurring sequences matched by short codes are stored in highly reliable memory states, while rare sequences matched by long codes are written normally.

Highly reliable states are achieved by using a TLC cell, typically one of eight states, to store one of seven or even six values. Of course, this reduces the information capacity, but increasing the voltage step between states significantly increases the reliability and storage time.
