Strata (LoRa 915 MHz)
The Strata LoRa board is a low-power wireless sensor node for LoRaWAN™ applications featuring Microchip ATmega32U4 microcontroller, barometer, ambient temperature sensor, and humidity sensor. This board is perfect for engineers and makers looking to test and prototype possibilities of LoRaWAN technology.
Once you have tested the board, you may use Geppetto online to design and customize it for your own project.
Strata - LoRa® Weather Station Node (915 MHz)
Put your IoT application where it needs to be with Low Power Wide Area Network (LPWAN) technology and LoRa®. The Microchip RN2903 provides an on-board LoRaWAN™ protocol stack for easy IoT integration. The Strata node can connect to any public LoRa® gateway on your IoT application's network to deliver data from anywhere.
The LoRa Transceiver module used in this board can be applied to automated meter reading, home and building automation, wireless alarm and security systems, industrial monitoring and control, and internet of things (IoT).
Important: 902 - 928 MHz frequency band is reserved for North America.
