Using RFM95 module based on SX1276 Wio for Long Range Application Inputting voltage: 5V/3.3V ~28mA(Avg) @+20dBm continuous transmit ~8.4mA(Avg)@standby mode ~20mA(Avg) @receive mode, BW-500kHz

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.

The main functional module in Grove - Long Range Radio 868MHz is RFM95, which is a transceiver that features the Long Range modem that provides ultra-long range spread spectrum communication and 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.

There we already integrated a simple 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.
