Picade 2 Player Version

Picade is the best solution using a Raspberry Pi in a Arcade Environment like Bartops, Barcade with MAME or retroarch.

Features:

Works with Regamebox, Recalbox, Retropie and other distributions
28 Inputs possible!
On Board Amplifier!
On Board Amplifier can be controlled via Buttons. So no need to assemble a potentiometer in your cab. Just use buttons.
On Board Amplifier can be controlled alternatively via Software and GPIO. With this option there is no need of extra buttons fpr volume control at all.
Volume control otions are set on the board via DIPs. So no need to make software configurations.
Extra 5 Screw Terminals for GND. This make your wiring simple :)
Needs only 5V, So you save bare money, because you don't need a 12V PSU anymore.
Sound is conneced via line in headphone jack. So no GPIO are occupied by custom sound interface solution and no extra drivers or DT Overlays are neeeded.
