 ## LCD Selection
 Initially I was planning to use the [NHD-2.4-240320DA-CTXN](https://www.digikey.com/en/products/detail/newhaven-display-intl/NHD-2-4-240320DA-CTXN/26743729) but I found that it requires 9.0V to drive the back light. Since I am driving this off of a single cell lipo I didn't want to add the additional complexity of another boost converter to get to 9.0V. I was able to find [another very similar display](https://www.digikey.com/en/products/detail/newhaven-display-intl/NHD-2-4-240320AF-CSXP/22204988) that instead uses 3.0V (up to 3.3V) to power the back light.
 
-The display controller gives the option of using SPI or parallel RGB to control the display. I decided to go with SPI since it is much simpler to route and manage and I don't need the performance gained by the parallel RGB interface.
