KA06 - wich pins are used?

Hi there,

Sorry for posting here but there isn’t a General topic for KA06

I am programming the LCD and want to know wich pins are used by the board and wich (digital) pins are free to use to attach a lets say micro speaker.

When i look at the connection diagram i can’t see wich pins are used and wich aren’t.

Please have a look at page 10 of the manual, it features a pin info table.
