MKS TFT28 and Arduino Mega 2560 (CH340G) Fix

Description

Some Time Ago I Solved Problem With Serial Communication Of The External Display Module Mks Tft28 With The Chinese Clone Arduino Mega 2560 (On Ramps Connector Aux-1). After Thoroughly Analyzing Circuit With The Ch340G (Usb Uart), I Found The Cause Of This Problem. It'S A Bad Application The Ch340G On The Arduino Board. Modification Requires Removal Of Resistors R10, R11 And Replace R12, R13 (680Ω). The Only Minor Cosmetic Deficiency Of This Modification Is The Disfunction Of The Rx And Tx Leds, Which, Of Course, Has No Negative Effect On The Functionality Of Serial Communication With The Arduino.
