+# How to make modern KORAD
+You actually need to replace the display board with a new LCD. The project is based on the low cost ESP32 development board. The board WT32-SC01 with 3.5 inch 320x480 capacitive multi-touch LCD Screen and built-in Wifi. 
+Also you need an external wifi antenna and a DC-DC converter (12v -> 5v, 1A).

+![DC-DC converter](/Pictures/dc_dc.jpg)
+
+There are two options for the board:
+1) WT32-SC01 - recommended
+2) WT32-SC01 PLUS - is not recommended due to its size.

+## How to flash the board (2 ways)
+1. Use finished firmware files from the folder **Binary**. Upload Flash Download Tools  from official page: https://www.espressif.com/en/support/download/other-tools
+Connect USB cable to your development board, run the application, select COM port and bin-file. When download is completed push "RST" (Reset) button to restart your dev board.
+2. Use Visual Studio Code + Platformio. Open project from **VSCode** folder. Build and upload the project.

+## How it works
+The project is suitable for all models KA3005D and KA3005P. Models without programmable control (KA3005D) will work, but you will not be able to control the current values and voltage.
+Although KORAD3005D is not intended for programmable control, nevertheless, some of the devices can work like KORAD3005P. Under the cover on the printed circuit board there is a connector for communication via UART. Let's call such devices that can be controlled via UART KORAD3005DP.
+To see the difference between KORAD3005D and KORAD3005DP, just listen to it. Watch this short video and you will hear the difference.
