Seeeduino RHF76-052AM Dev Board

Seeeduino Long Range is an Arduino development board with Long Range protocol embeded, through which you can get started quickly to experience Long Range advantage in the field of IoT. 

Based on communication module RHF76-052AM, Seeeduino RHF76-052AM is compatible with Long Range Class A/C and supports a variety of communication frequencies. The 4 onboard standard grove connectors allow Seeeduino RHF76-052AM to connect with hundreds of grove sensors and actuators for Seeeduino conveniently, as a result, users are able to be more focus on the application itself without worrying about the compatibility issue between different modules.

In addition, the board has embeded an integrated lithium battery management chip that allows the board to be charged by USB interface. In low consumption mold, a full charged lithium battery can power the board for several months. By using Seeeduino RHF76-052AM. You can build an IoT application very quickly.

We also offer another version with GPS module embeded, click here to find the Seeeduino RHF76-052AM W/GPS.

Note:

Please update the firmware when the first time to use it. Please always plug 3.7V Lipo battery in case USB power supply is not sufficient.
