2003T 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 2003T, both are designed with ZLAN1003 single chip, but 2003T is larger and has more extendable pins. The operation temperature of 2003T is lower than that of 2003T.
Compared with ZLSN2002, the two use the same pin distribution, but the 2003T has more functions, including web page download, program upgrade via Ethernet port, etc. It can be used for upgrading ZLSN2002.
