LEAPPAD:
Example-Video: https://www.youtube.com/watch?v=LtUhENu5TKc
The LEAPPAD is basically compareable to the SEGA PICO, but without
Screen-Output! Each "Game" consists of two parts (Book + Cartridge).
Insert the cartridge into the system and add the Book on the Top of the
"console" and you can click on each pages and hear sounds or
learning-stuff on each page...
MY FIRST LEAPPAD:
Basically the same as the LEAPPAD, but for even younger kids! (Cartridge
internal PCB's are identical to LEAPPAD).
Example Video: https://www.youtube.com/watch?v=gsf8XYV1Tpg
LITTLE TOUCH LEAPPAD:
Same as the other LEAPPAD models, but aimed at babies.
Don't get confused by the name "LEAPPAD", as it looks like Leapfrog
also released some kind of Tablet with this name, and they even released
a new "LEAPPAD" in around 2016:
https://www.youtube.com/watch?v=MXFSgj6xLTU , which nearly looks like the
same, but is most likely techically completely different...
The cartridges pinout is the same on the three systems:
