Altitude Tech IronLink LoRA 915MHz Development Board

Altitude Tech IronLink LoRA^® 915MHz Development Board is an industrial Low-Power Long Range - LoRa Technology transceiver based on the Microchip RN2903 module. This transceiver enables devices like sensors and embedded computers to connect to the internet. The IronLink LoRA board complies with the LoRaWAN Class A protocol specifications by integrating RF, baseband controller, and command Application Programming Interface (API) processor. This makes it a complete long-range solution. Altitude Tech IronLink LoRA 915MHz development board features a 902MHz to 928MHz frequency range and FSK, GFSK, and LoRa technology modulations. Applications include automated meter reading, smart agriculture, smart healthcare, Internet of Things (IoT), home and building automation, industrial monitoring and control, and Machine to Machine (M2M).
