Serial Ethernet Module Introduction

This is a serial TTL to Ethernet module, used for data transparent transmission.USR-TCP232-ED2 is a triple serial ethernet module, which supports 3*TTL working at the same time.It is based on the Cortex-M4 solution and its basic frequency is up to 120MHz. And the internally the module integrates TCP/IP protocol stack.
