Notes:

• The MicroSD Memory must be formatted in FAT32.
• The images must be with png extension and in 320x480 resolution
• The battery level indicator is in development (Fixed value of 99% is indicated)

Possible improvements in the future

• Add Lipo Battery Rechargeable (View state on screen)
• Sleep mode (Screen Off) / Alarm clock (Speaker)
