Introduction of Ethernet Modules ST-TCP-ED21
This is a serial TTL to Ethernet module, used for data transparent transmission. ST-TCP-ED21 is a triple serial ethernet module, which supports 3*TTL working at the same time. It is based on Cortex-M4 solution and its basic frequency is up to 120MHz. And the internal of the module integrates TCP/IP protocol stack.

Ethernet to UART modules ST-TCP-S21 can transmit data transparently between TCP/IP and TTL, which can be applied in RS232/ RS485 by level shift circuit. ST-TCP-S21 is a tiny size embedded Ethernet Module which can realize data bidirectional transparent transmission between TTL and Ethernet Port.
