Item Details:

RA-02 LoRa Wireless 433MHz Module using the Semtech SX1278 chip with a standard U.FL(IPX) antenna connector. The software configures the frequency and can be configured for 410 to 525MHz. The SX1278 is a revolutionary new chip enabling wireless communications at distances up to 15km, using Semtech\'s LoRa(Long Range) technology. This chip also supports high-performance (G)FSK modes for systems, including WMBus, and IEEE802.15.4g.

At the same time, compared with the traditional modulation technology, LoRa™ Modulation technology in anti-blocking and selection also has obvious advantages. Solving the traditional design can not consider the distance, interference, and power consumption.

Features

• LoRaTM spread spectrum communication
• +20dBm - 10mW. Stable RF output power when input voltage changed
