-# W55RP20-S2E README
+## Overview
 
-> The W55RP20 is a System-in-Package (SiP) developed by WIZnet, integrating Raspberry Pi's RP2040 microcontroller, WIZnet's W5500 Ethernet controller, and 2MB of Flash memory into a single chip. 
- This repository contains firmware that implements Serial to Ethernet using the W55RP20.
+The **W55RP20-S2E** is a pre-programmed product with an Serial to Ethernet FW and a valid MAC address into the [W55RP20](./../overview.md).
 
-These sections will provide how to configure development environment to develop and modify W55RP20-S2E.

+### 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](#customization-services)** such as change / add functions by customer request.
+

+
+## Features
+
+**The following key features are included with the W55RP20-S2E product.**
+
+  - Easy to add Ethernet networking function through UART interface
+        of any device / MCU
+    - Support **RS-232C** and **RS-422/485** if an external circuit is configured.
+    - Configurable via Ethernet(Web config, WIZnet Configuration tool) and AT command.
+  - Support multiple protocols
+    - SSL TCP client
+    - MQTT client
+    - MQTTS client    
+  - Support protocol conversion between modbus RTU/ASCII and modbus tcp 
+  - Support serial data packing
+  - Support TCP connection password
+  - Unique **MAC Address** (WIZnet OUI)
