The LoRa Long Range Transceiver Shield 433 MHz is based on the RFM98W 433MHz module, which is a long range transceiver on a Arduino shield form factor and based on Open source library.
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.
Have only done some preliminary tests but so far so good. If used as is, it can only be used with Arduino UNO. Can be modified to work with Arduino Mega 2560 by cutting pins 11, 12, 13 (on the shield) and connecting them to the ISP pins (on the shield). Can still be used with UNO after this modification.
