Developed by Ai-Thinker company, the manufacturer of the ESP32S, this Ra-01 LoRa (Long-range Radio) module will take your IoT projects the distance with communication over a long-range spread spectrum.
This module uses SX1278 IC and works on a 433MHz frequency. Frequency hopping—which gives you that sweet balance of quality signal transmission—will cover a range of 420-450MHz. This long-range wireless capability is packed into a small (17 x 16mm) package and delivered through a spring antenna.
This form of wireless communication results in a larger bandwidth, increasing interference resistance, minimizing current consumption, and increasing security. At the same time, compared with the traditional modulation technology, LoRa™ Modulation technology in anti-blocking and selection also has obvious advantages, to solve the traditional design can not take into account the distance, interference, and power consumption.
