Grove - LoRa Radio 433MHz
This is the Grove - LoRa Radio 433MHz, which can be used for 433MHz communication. You can also find the version for 868MHz at Grove - LoRa Radio 433MHz.
Grove is a very powerful platform developed by Seeed Studio to simplify your IoT projects.We have integrated the grove connector to most boards produced by Seeed to make them become a system. This time, we combined Grove with LoRa to provide an ultra-long-range wireless module for you.
The main functional module in Grove - LoRa Radio 433MHz is RFM98, which is a transceiver features the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst mini-missing current consumption. The heart of Grove - LoRa Radio 433MHz is ATmega168, a widely used chip with very high-performance and low power consumption, especially suitable for this grove module.
There we already integrated a simple wire antenna to receive signal, if the signal is too weak to receive, don’t worry, the MHF connector next to the antenna is for adding a second antenna which has MHF interface to gain more signal.
- Please keep the antenna vertical to the board and as straight as possible to make 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.
