Elfin-EW11A
RS232/RS485 to Wi-Fi
The Elfin-EW1X provides RS232/RS485 interface to Wi-Fi connectivity. The Elfin-EW1X integrate TCP/IP controller, memory, high-speed serial port and integrates a fully developed TCP/IP network stack and mbed OS. Elfin-EW1X also support remotely configure, monitor with IOTService.
The Elfin-EW1X using highly integrated hardware and software platform, it has been optimized for all kinds of applications in the industrial control, smart grid, personal medical application and remote control that have lower data rates, and transmit or receive data on an infrequent basis.
The Elfin-EW1X integrates all serial to Wi-Fi functionality with 61 x 26 x 17.8mm size.
