SMD 5x7 Matrix Display
That is the pcb layout of the 5x7 matrix display with a ATMega8L MCU.
Dip switch #1 is for switching on/off teh power. Dip switch 2-4 selects up to 7 different program sections.
All characters are stored in the EEprom section of the ATMega8 and do not need and flash or ram memory!
see a small demo video (about 4 MB)
For defining the characters i wrote a small visual basic program which makes the definition very easy.
