*The LoRa module RN2903 is being loaded with Malaysia LoRaWan frequency and specification, it can only work from 919MHz to 923MHz. To make it works, a proper gateway and LoRaWAN server (Malaysia Frequency) must be available. We do not recommend getting this shield if you do not have proper LoRaWAN server. We are still working with many parties to get the LoRaWan ecosystem up, but it will require time and resources. If you want to try LoRa technology, please be patient or get two shield to do point to point communication.
is the latest wireless technology, stand for Lo
nge, it fall under the Low Power Wide Area Network technology which is developed for IoT. This shield is the LoRa node shield, it is build in with the Microchip RN2903
915MHz LoRa module. RN2903 is a long range transceiver and we customized it to be a Arduino shield form factor. The Lora Shield allows the user to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.The RN2903 module complies with the LoRaWAN Class A protocol specifications. It integrates RF, a baseband controller, command Application Programming Interface (API) processor, making it a complete long range solution.
The Lora Shield based on very realible Microchip fully certified RN2903 module targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.
Using Microchip RN2903 module, this Lora Shield can achieve a sensitivity of over -148dBm. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa technology is ideal for battery-operated sensors and low power applications such as IoT, M2M, Smart City, Sensor networks, Industrial automation, and more.
The RN2903 is embedded with LoRaWAN™ Class A protocol enables seamless connectivity to any LoRaWAN compliant network infrastructure, whether public or privately deployed. With the LoRaWan protocol on this shield, it further free up your Arduino program memory for user program.
