LoRa Modules are long range low power RF Modules. Great for IoT applications to send sensor data to the cloud over long ranges.
Developed by our team Ai-Thinker, the manufacturer of the ESP8266 and ESP32 wifi modules, this Ra-01 LoRa (Long-range Radio) module will take your IoT projects the distance with communication over a long-range spread spectrum. This form of wireless communication results in a larger bandwidth, increasing interference resistance, minimizing current consumption, and increasing security.
This module uses SX1278 IC from SEMTECH and works on a 433MHz frequency. Frequency hopping—which gives you that sweet balance of quality signal transmission will cover a range of 420-450 MHz. With the LoRa Ra-01, you don’t have to compromise in the balance of range, interference immunity, or energy consumption. The technology behind this IC means that it's perfect for those projects requiring range and strengt
