Description
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.
This is the 433MHz version, which can be used for 433MHz communication. You can
also find the version for 868MHz at
Grove - LoRa Radio 868MHz.
Note:
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.
