The main module in the Radio RFM98- SX1276, which is a transceiver implementing s the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst mini-missing current consumption. The second processor ATmega168, a widely used chip with very high-performance and low power consumption, especially suitable for this grove module. This processor is to handle the serial to MISO Interface internally.
The module comes with an integrated simple wire antenna to receive signal. if you want a larger antenna, there is a second MHF connector next to the antenna.
This is the 433MHz version, which can be used for 433MHz communication.
Please keep the antenna vertical to the board and as straight as possible to have the best transmission and receive range.
Avoid large metal objects near the antenna.
