The Grove - LoRa Radio 433MHz module has a RFM98 module, which is a transceiver featuring the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. The heart of the Grove - LoRa Radio 433MHz is an ATmega168, a widely used chip with very high-performance and low power consumption, especially suitable for this grove module.
A simple wire antenna is wired on-board to receive signal. If the signal is too weak to receive, don’t worry, the MHF (U.FL) connector next to the antenna is for adding a second antenna to gain more signal.
This is the 433MHz version, which can be used for 433MHz communication. We also have a 868MHz here.

- Please keep the antenna vertical to the board and as straight as possible to get the best performance.
- Please avoid making any big metal object near the antenna and a metal cape is also not recommended if you need to add a cape for your device.
