LoRa Module Ra-01

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

Applications Of RA01 LoRa Module
· Remote control and data collection system
· AMR(water meter, ammeter and gas meter) automated meter reading
· Wireless handheld unit, oil field, mining area, construction site, factory
· Industrial data collection, transmission and intelligent control
· Wireless alarm system
· Smart home system
· Baby monitor, Hospital calling system
· Small size wireless data terminal

Note: When laying out the board, try to put the module on the side of the board with the antenna facing outward. No components should be placed at the bottom of the antenna or near it. The module should be as far away as possible from power components and electromagnetic components, such as thyristors, relays, inductors, buzzers, and horns.
