Evaluation and Demonstration Boards and Kits play an important role in electronic system development, and provide an effective way for engineers to test functions and system performance of their designs. Among all, the WIZ140SR-EVB (WIZ140SR Evaluation Board) from Wiznet is a comprehensive evaluation and development solution for network data communications that support a wide range of applications. It is designed with the advanced Internet protocols including IPv4, IPv6, SSL, UDP, TCP, DHCP, DNS and support various interfaces, such as USB, RS-485, CAN, and Ethernet. With these features, WIZ140SR-EVB is widely used in various application fields such as remote control, monitoring, data acquisition, industrial automation, HVAC system, etc.

In terms of working principles, the WIZ140SR-EVB consists of an Ethernet port and the WIZ140SR network module which is connected with a host processor, such as ARM Cortex-M3, via standard UART interface. Ethernet port is used to connect to a network, while the WIZ140SR module consists of an Ethernet controller, 8KB SRAM, and 32KB ROM that enable users to gain access to the Ethernet easily. The communication between Ethernet and the host processor is established through the UART interface. During communication, the host processor sends the signal to the UART and the WIZ140SR module transforms it into an Ethernet packet. Afterwards, the Ethernet controller transmits the packet into the Ethernet and returns the response. Comparatively, the host processor receives the response from the UART. The whole process is a simple two-stage communication that saves more time and provides higher efficiency.

To sum up, WIZ140SR-EVB is a powerful and versatile evaluation and demonstration board which features reliable connection compared to most of the other models. With features such as IPv4, IPv6, SSL, UDP, TCP, DHCP, and DNS, it is widely used in various applications, from remote control and monitoring to industrial automation, and HVAC system. Its simple two-stage communication mechanism also allows users to quickly establish connection and communicate with the device. As such, WIZ140SR-EVB is an ideal choice for designers who aim to develop and test their designs.
