The display layout is designed to adapt an LCD Display (e.g. Displaytech 162A/B) to an STK500/STK600 or Basys3 development board. It also support different input voltages. If the STK500/STK600 connector is used, it is necessary that the board gets 4.5V - 5.5V, otherwise it would not work. If the Basys3 connector is used the input voltage can be 1.5V to 3.3V, the board needs an external power supply (5V) through the DC Jack!
