2003B The new generation serial port to Ethernet core module,
is an embedded module that connects Ethernet (TCP/IP) through serial port (TTL level UART). You can transparently convert the serial data to the TCP/UDP data. It adopts the latest generation of ZLAN1003 single-chip solution of Shanghai ZLAN, it has many functions such as: 100 TCP connection, DNS, DHCP, web custom download and so on. The inside of 2003B module has integrated network transformer, the Ethernet pin directly connecting network cable can be ok. In addition, the default power supply of 2003B is 3.3v, can also provide 5V module.
Compared with ZLSN2003B, both are designed with ZLAN1003 single chip, but ZLSN2003B is larger and has more extendable pins. The operation temperature of ZLSN2003B is lower than that of ZLSN2003B.
Compared with ZLSN2002, the two use the same pin distribution, but the ZLSN2003B has more functions, including web page download, program upgrade via Ethernet port, etc. It can be used for upgrading ZLSN2002.
