+# IoT Core OS V3
+This is an OS for the ESPMega PRO R3 Programable Logic Controller
+
+## **Compatibility**
+1. **CPU**
+    - ESPMega PRO R3.0a/b
+    - ESPMega PRO R3.1a
+    - ESPMega PRO R3.2a/b/c
+2. **CPU Add-ons**
+    - ESPMega PRO Internal Display Module
+    - ESPMega PRO External Touch Display Module
+3. **Add-on Cards**
+    - ESPMega I/O Analog Expansion Card
+    - ESPMega I/O IR Expansion Kit
+    - ESPMega I/O Card Hub
+    - ESPMega I/O UART Multiplexer [WIP]
+    - ESPMega I/O Digital Expansion Card [WIP]
+
+## Features
+- Internal Touch Display support for diagnostics and configuration
+- WebUI for Configuration and OTA Update
+- Allowing for reading and writing to registers from MQTT
+- Provides abstraction layer to the MQTT protocol and internal components
+
+## User Code and 3rd Party Extension
+This OS allows the user to write custom program for the device to run in the OS<br/>
+### *usercode.hpp* and *user_code.cpp*
+### I/O Abstraction Layer
+### MQTT Abstraction Layer
+### RTC and Clock Abstraction Layer
+### Persistent Storage Abstraction Layer
+### Climate Abstraction Layer
+### Energy Monitoring Abstraction Layer
+### Timer Abstraction Layer
