SME291
Serial - UDP Ethernet Converter Module with RJ45

This product is not available.

Serial Ethernet products are being replaced with more fetaured designs.

New designs will be on sale after April 2012. 

SonMicro Serial UDP Ethernet converter modules come with two hardware options both have the same firmware. One is called SME290-Mini and the other is SME291. SME291 is a compact module integrated with 5V regulator circuit and the LF1S022 RJ45 Ethernet connector. SME291 module may be used apart from the device or PCB. It requires only power supply pins and UART TX/RX pins to the main device or circuit. This is the more practical option if compared with SME290-Mini module. SME291 can be used inside the product enclosure or can be connected externally.

SME290/291 is a true Serial-to-Ethernet converter that connects a serial device to the LAN/WAN or internet, based on UDP protocol. Unlike TCP/IP , UDP protocol is a connection-less protocol, is similar to UART / RS232 and can be a better choice for embedded and industrial applications in most cases.

SME290/291 does not require any external microcontroller or PC to be controlled; it simply translates Ethernet and Serial data to each other with the minimum latency based on UDP protocol.
