DESCRIPTION

This TinyShield is designed specifically for the TinyScreen+ to allow for video playback in a very compact package.  This TinyShield adds a microSD Adapter to store video and image files, an audio amplifier for driving a speaker, and an IR receiver.  The 16x9 speaker is also included with this board and can be connected to the speaker port.  

Note: This does not include the microSD card (sold separately), you can get a compatible microSD card here.
