A small TFT display provides excellent feedback for the user. It can be used to display the current status of the device, or to display the current settings.
The latest version of the Pod uses the Adafruit 1.3" TFT display. This display is a 240x240 pixel display with a 16-bit color depth. It is a wide-angle display, which means that it can be viewed from a wide range of angles without the image becoming distorted.
Detailed connection instructions are available on the Adafruit Website, basic pin connections are shown below.
