Altitude Tech IronLink LoRA 868MHz Development Board

Altitude Tech IronLink LoRA® 868MHz Development Board is an industrial Low-Power Long Range - LoRa Technology transceiver that is based on the Microchip RN2483A 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 868MHz development board features  863MHz to 870MHz and 433.050MHz to 434.790MHz frequency ranges 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).
