RAK811 is a budget LoRa module for the Internet of Things

08.12.2018

The new RAK811 radio module from RAK allows you to build a star-type radio network or implement a simple exchange between two points with a minimum of engineering costs. The module includes an SX1276 RF transceiver, a low-power STM32L151 microcontroller and allows you to organize data transmission over a distance of up to 5 kilometers in urban areas. The RAK811 differs from other LoRaWAN modules with an additional low-noise amplifier, a highly stable TCXO reference oscillator, and full shielding of all electronic components.

The module is controlled using simple AT commands, while RAK811 can work both in LoRaWAN networks and in simple p2p (point-to-point) mode. The built-in FW can be replaced with your own code (CoIDE/Keil5) - examples of finished projects for RAK811 can be found on GithHub (opensource). The module supports the Arduino platform and several official sketches are available for it - connecting to the LoRaWAN network and testing the communication range (ping-pong test).

RAK811 module features:

LoRaWAN protocol in the 868 MHz band;
Activation via OTAA/ABP modes;
LoRa/FSK/GFSK/OOK modulation;
Point-to-point mode (Lora Point to Point communication);
LoRa technology allows you to recognize the signal 20 dB below the noise level;
Sensitivity down to -148 dBm guarantees maximum range;
Communication range up to 15 km in open space;
Adjustable output power from 5 to 20 dBm;
Low consumption (500 nA) - up to 10 years of battery life;
Support for different frequency channels;
Customizable control interface via UART;
Simple text AT commands or native application;
Consumption 60 mA (TX); 9,9 mA (RX);
Dimensions 22x14x1,7 mm;
Operating temperature -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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Neurocomputer interface implanted in human 30.07.2022

The brain-computer interface has become a reality in the United States (albeit limited so far). Synchron says it has become the first company in the country to successfully implant a brain-machine interface into a human.

Doctors at New York's Mount Sinai West Medical Center implanted a Stentrode device into the motor cortex of a patient who agreed to take part in the COMMAND experiment sponsored by Synchron. Its purpose is to evaluate the usefulness and safety of brain-computer interfaces in enabling people suffering from severe paralysis to control the device without using their hands.

Ideally, Stentrode's technology should enable these people to self-send emails, text messages, and perform other digital tasks that healthy people take for granted.

Surgeons installed the implant through an endovascular procedure that avoided major open-brain surgery by inserting it through the jugular vein. The operation went "extremely well" and, according to Synchron, the patient was able to return home within 48 hours. The ongoing experiment in Australia is also going well, with four patients who received implants a year ago doing well.

It is clear that by the time when doctors can offer the installation of Synchron brain-computer interfaces to all patients in need, a lot of time will pass.

In July 2021, the company received approval from the US Food and Drug Administration (FDA) to perform an interface implantation operation in humans under the COMMAND pilot program, which is still active at the time of this writing.

The US procedure was a significant step forward. It will allow people suffering from paralysis to regain the ability to independently control their lives. It also testifies to the victory of Synchron in the competition - Elon Musk, for example, has not yet received FDA approval for the use of implants developed by his company.
