I picked up 3 Gamepi15 hat's from WaveShare

GamePi15

This nifty little game hat expands on the existing modules used in PinkyPi and PinkyPi Pro, but ingrates all the needed hardware into 1 place.

1.54inch LCD

Headphone Jack

Battery and Charger

Amp

Speaker

I've since started working on the new case design as the foot print of this device is a hair bigger than the others.

Trigger buttons and other buttons have moved abit, and the joystick has been replaced with a 4way D-Pad

I will be working on a new case design as well as video driver pack and a pre-built RetroPie Image to add to the PinkyPi line up.

**EDIT**

Case is available for download on Thingiverse
