| + | 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. | ||
