Expansion board X-NUCLEO-IDS01A4

13.02.2016

The new X-NUCLEO-IDS01A4 expansion board from STMicroelectronics allows you to add wireless data transfer functionality to any project that is being developed based on Nucleo boards with STM32 microcontrollers. The X-NUCLEO-IDS01A4 board has a SPSGRF-868 radio module with a chip antenna, which completely eliminates the need for an engineer to work with high-frequency components. The board is made in the Arduino Shield form factor, compatible with MORPHO and Arduino UNO R3 family connectors.

The interface with the control microcontroller is carried out through the SPI and GPIO lines. The designer can change some of the GPIO lines by soldering the resistors on the board specifically provided for this purpose. The board additionally has an M95640-R 64 Kbit serial SPI bus EEPROM memory chip, which can be used, for example, to store user settings related to the use of the SPIRIT1 transceiver.

Due to the fact that the board uses the most popular and affordable 2,54 mm pitch connectors, X-NUCLEO-IDS01A4 is easy to connect to your own design board or even to solderless prototyping boards to quickly create a working device prototype. The low price of the expansion board allows it to be used not only in prototypes, but also in small production batches.

The X-NUCLEO-IDS01A4 board is supported by the STMCube software package, which includes the STM32CubeMX graphical code generator. The special X-CUBE-SUBG1 plug-in allows you to quickly and easily create a working wireless transceiver code for any STM32 microcontroller. The board has been tested by the manufacturer with the NUCLEO-L053R8 and NUCLEO-F401RE boards, which are based on low power microcontrollers.

X-NUCLEO-IDS01A4 Features:

Built on the basis of the SPSGRF-868 (ETSI-certified) module;
Compatible with Spirit1 Library and STM32Cube firmware;
Code examples for NUCLEO-L053R8 and NUCLEO-F401RE;
Integrated balun BALF-SPI-01D3 and chip antenna;
Memory M95640-R 64 Kbit serial SPI bus EEPROM;
Operating voltage 1,8 ... 3,6 V.

Software developers are offered a ready-made point-to-point wireless link project, which is included in the X-CUBE-SUBG1 extension software package (for STM32Cube). The software runs on STM32 and includes drivers that implement a radio channel in the sub-1 GHz range for SPIRIT1 and the SPSGRF-868 module based on it. The X-CUBE-SUBG1 software is built on the STM32Cube software technology to facilitate portability between different STM32 microcontrollers.

The software comes with examples of implementation of P2P and WM-Bus communication protocols that work on the X-NUCLEO-IDS01A4 expansion board when connected to the NUCLEO-F401RE or NUCLEO-L053R8 boards. The WM-Bus communication protocol is only available for the X-NUCLEO-IDS01A4 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, ... >>
