W7500(P) which WIZ750xx S2E firmware is programmed on


The W7500(P)-S2E is a chip product that has the firmware programmed in the WIZnet W7500 / W7500P MCU. This product includes the latest 'WIZ750SR serial to Ethernet module' firmware for widely used in various applications around the world

WIZnet S2E Solution

  • WIZnet 'Serial to Ethernet' product is a protocol converter that transmits data sent by serial equipment as TCP/IP data and converts the TCP/IP data received through the network back into serial data to the serial equipment.
  • With this product, it is possible to easily add an Ethernet networking function to a device supporting UART interface, the devices can be controlled via an Ethernet network - Internet.

We also provide Customization Services such as change / add functions by customer request.
