Ai Thinker Ra-01SCH-P LoRa Module SX1276 Based Long-Range Wireless Transceiver with SPI Interface

Description:

Ra-01SCH-P is a LoRa series module designed and developed by Shenzhen Ai-Thinker
Technology Co., Ltd. This module is used for ultra-long-distance spread-spectrum communication. Its RF chip LLCC68+ mainly uses LoRa™ long-range modem for ultra-long distance spread spectrum communication, with strong anti-interference and the ability to minimize current consumption. With the help of SEMTECH’s LoRa™ patented modulation technology, the module has a built-in power amplifier (PA) and low noise amplifier (LNA) on this basis, with high sensitivity exceeding -137dBm, +29dBm transmission power, long transmission distance, and high reliability.

At the same time, compared with traditional modulation technology, LoRa™ modulation technology also has obvious advantages in anti-blocking and selection, solving the problem that traditional design solutions cannot take into account distance, anti-interference, and power consumption at the same time.
