 +====== Hardware ======
 +ATmega328 is the main brain which can parse the stream from UART to show the data on the TFT-LCD.\\
 +The UART is connected to the host PC or ODROID via CP2104 which converts the UART to USB interface.\\
 +The CP2104 also has 3.45V voltage regulator to supply the power for LCD too.\\
 +With the on-chip regulator we could simplify the board design.
