MicroSD/Audio TinyShield [Discontinued]
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 16×9 speaker is also included with this board and can be connected to the speaker port.
Note: This does not include the microSD card. You can get a compatible microSD card here.
