“Used to access MP3 players, for sound effects for Animation on a Garden Railway.
Soldered header pins, ADKey board has a dual-use,
a) as a Keypad for use with AD key connection,
b) as GND connection to a Sound Card.
Simple and effective, good tactile touch when operating the keys.
Good product, inexpensive, no doubt other uses will be found for the keyboard around the Garden Railway.”
