ESP32-PICO-D4 - the smallest ESP32 WiFi module

06.06.2019

The ESP32-PICO-D4 is the smallest WiFi module in the entire Espressif ESP32 line. The module is released in the QFN-chip (SiP) form factor and has dimensions of 7,0x7,0x0,94 mm. ESP32-PICO-D4 is based on Xtensa LX6 dual-core processor. The ultra-compact 48-pin package houses the ESP32 crystal, crystal, 32 Mbit (4 MB) flash memory, TVS protection diode, and LC binding elements. The module does not require the connection of external elements, with the exception of the antenna, which makes it possible to implement the most miniature Internet of Things devices on its basis. In addition to WiFi 802.11 b/g/n, the module also supports Bluetooth v4.2 BR/EDR/BLE.

The output power of the module reaches 100 mW. The recommended supply voltage range is 2,7 ... 3,6 V, while the power source must be capable of delivering current up to 0,5 A. To quickly get acquainted with the capabilities of the module, you can use the ESP32-PICO-KIT debug board

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, ... >>

Effect of caffeine on drug resistance 17.09.2020

Researchers at the University of Edinburgh conducted a large-scale experiment to study the effect of caffeine on drug resistance.

For a long period of time, scientists believed that drug resistance could only develop after some kind of change in the DNA. However, a recent scientific study has made it clear that this is not actually the case. It turned out that under the influence of caffeine, epigenetic changes appear in fungi. The difference between epigenetic and genetic changes is that they do not change the genetic code itself, but the so-called packaging of the DNA helix.

The study was conducted on yeast treated with caffeine. According to experts, some genes were packaged in heterochromatin, which suppresses the activity of other genetic sequences. As a result, the body's resistance to drugs was formed.
