Ra-02 is a wireless transmission module based on SEMTECH's SX1278 wireless transceiver. It adopts advanced LoRa spread spectrum technology, providing a communication distance of 10,000 meters. The module has a strong anti-jamming ability and features air wake-up consumption. The SX1278 RF module is ideal for long-range spread spectrum communication, with minimized current consumption. With a high sensitivity of -148 dBm and a power output of +20 dBm, it ensures long transmission distances and high reliability.
LoRa modulation technology offers advantages in anti-blocking and selection compared to traditional modulation technologies. This makes it suitable for applications like meter reading, smart home systems, and burglar alarm equipment, covering a large number of users in a district environment.
The module supports various modulation modes, automatic RF signal detection, and has a small footprint dual-row stamp-hole patch package with a shielded housing and spring antenna.
