Ewon's Flexy is an industrial M2M router that lets OEMs and system integrators link remote devices in environments where communication technologies are constantly changing (2G, 3G, 4G, Wi-Fi). The unit’s base modules can contain up to four expansion boards, giving users everything from a simple serial, MPI or Profibus gateway to Ethernet to the Wi-Fi LAN router with redundancy via a 3G modem.
