First version of Pedaless Dashboard contain two atmega328 connected between with SoftwareSerial because left atmega328 is in this case GPS module because he reading from GPS and sending that information to right atmega328. Why im using separate atmega328 is because it need around 3 seconds to read GPS signal, and i cannot give 3 seconds delay for transmitting.

Right atmega328 is connected with wireless transceiver, OLED Display, Buttons and analog Throttle. Three buttons are Up / Down / Menu. Up and Down is to setup some settings or use like digital throttle, if you hold two buttons few seconds it will make reset in settings, Menu is for changing screens types.
