LoRa™ or Long Range is a technique, spread spectrum modulation, that is derived from CSS or Chirp Spread Spectrum that is helping the users to communicate in low-power consumption. It gained popularity amongst the tech-people because of its easy and efficient communication within an economical budget.
LoRa™ created a spark in the tech-communities with its power and ability to perform the communication in the best possible way. A lot of tech-enthusiasts create projects like smart cities in a cost-saving budget that has exponentially created the demand in the market. There are a lot of devices that are based on LoRa™ to intensify the user experience with its efficiency and applications. Pico LoRa™ Expansion (868MHz) is one of the products that has recently been launched in the market by SB Components that already got people to get this product and build something better. If you do not have the idea about the LoRa™ or Pico LoRa™ Expansion (868MHz) then get ready for a wonderful experience of the LoRa™ world via this blog. 
What is LoRa™?
Before diving into the details of the Pico LoRa™ Expansion (868MHz), let’s first introduce the technology LoRa™ and its features to get the understanding of the device. LoRa™ stands for long-range and is based on the spread-spectrum technique, which is derived from chirp spread spectrum (CSS) technology and encodes data using wideband linear frequency modulated chirp pulses. LoRa™ is a wireless technology or technique that enables the users to communicate with the other devices in a long range with secure transmission of data under low cost. There are a lot of individuals who do not have the ideas about the band of LoRa™ as there are different modules for different frequency bands. In different regions, LoRa™ Technologies provide their services in different frequencies.
