Grove is a very powerful platform developed by Seeed Studio to simplify your IoT projects. We have integrated the grove connector into most boards produced by Seeed to make them become a system. This time, we combined Grove with Long Range to provide an ultra-long-range wireless module for you.
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
Highlighted Features
- The main functional module in Grove - Long Range Radio 868MHz is RFM95
- This transceiver features the Long Range modem
- Provides ultra-long range spread spectrum communication
- High interference immunity whilst mini-missing current consumption
- The heart of Grove - Long Range Radio 868MHz is ATmega168
- A widely used chip with very high-performance and low power consumption, especially suitable for this grove module
- Integrated wire antenna to receive the 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 that has an MHF interface to gain more signal
- 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
