"The supply crisis in the semiconductor field occurred because of the high demand for technology products, which brought tremendous pressure on the supply chain, but the supply chain was not prepared for this."

This device supports FSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation methods. It mainly uses LoRaTM remote modems for ultra-long-distance spread-spectrum communications with strong anti-interference. The SX1278 supports a maximum link budget of 168dB, a constant + 20dBm / 100mW RF power output when the voltage changes, and a 14dB high-efficiency power amplifier, that is, the device can output + 20dBm or + 14dBm RF power at the same time. The device has a programmable bit rate of up to 300kps, high sensitivity down to -148dBm, and has an excellent anti-blocker. Compared with similar devices, the SX1278 significantly reduces the current consumption and significantly optimizes the performance of phase noise, selectivity, and receiver linearity.

LoRa is a linear frequency modulation spread spectrum IoT modulation technology, also known as broadband phenomenon FM (Chirp Modulation) technology. Compared with the traditional FSK technology, LoRa has a longer transmission distance under the same power consumption, and has strong anti-interference ability.

Serial communication technology is to transmit data bit by bit in sequence, and only two data transmission lines are needed. Compared with parallel communication, although serial communication technology saves port consumption, it also reduces the data transmission rate.

Many people can't tell the difference between the LoRaWAN wireless module and the LoRa gateway wireless transmission technology, and what their application in the field of IoT is.

​ With the launch of IoT devices, longevity policies for communication products will be a huge obstacle, and most products such as infrastructure machinery or smart meters deployed in smart cities will struggle to connect to the corresponding devices. Although unsubscribed from the service, the network provider.

With the rapid development of technology, many entertainment programs have appeared. In order to achieve the effect of the program, judges often give scores to the performers below, and the scoring system has also developed from the original placard scoring to electronic scoring.

It was confirmed that Chengdu Ebyte Electronic Technology Co., Ltd. met the conditions of Chengdu's intellectual property advantage unit.
