Ai Thinker LoRa Ra-01SC Module

Looking for Lora Ra-01sc? Ai Thinker LoRa Ra-01SC Module is available at Zbotic with fast shipping across India.

The LoRa series module Ra-01Sc, created by Shenzhen Ai-Thinker Technology Co., Ltd., is utilized for ultra-long-range spread spectrum communication. It features the RF chip LLCC68, which primarily employs the LoRa remote modem for this purpose, offering robust anti-interference capabilities and low power consumption. The LLCC68 chip boasts a high sensitivity of over -129 dBm, a power output of 20 dBm, extensive transmission range, and high reliability due to SEMTECH’s patented LoRa modulation technique. In contrast to traditional modulation technologies, LoRa stands out by providing substantial improvements in blocking and selectivity, effectively addressing the challenges of balancing distance, interference resistance, and power consumption that conventional designs fail to meet.
