Ai-Thinker Ra-01SC LoRaWAN Module
The Ai-Thinker Ra-01SC LoRaWAN Module is an advanced communication module engineered for ultra-long-distance spread spectrum communication, making it a cornerstone for Internet of Things (IoT) applications. Built around the Semtech LLCC68 RF chip, this module leverages LoRa technology to deliver exceptional range, reliability, and power efficiency. With a sensitivity of -129 dBm and a maximum output power of +22 dBm, the Ra-01SC ensures robust connectivity in challenging environments, such as urban areas or remote locations.
Its low power consumption, with a minimum received current of 4.2 mA and a stand-by current of 0.6 mA, makes it ideal for battery-powered devices, extending operational life without frequent recharging or replacement. The module supports multiple modulation modes, including FSK, GFSK, MSK, GMSK, LoRa, and OOK, offering flexibility to meet diverse application needs.
