EOS S3 MCU IO Map to QuickLogic Thing Plus

Below is the graphical datasheet of the QuickLogic Thing Plus EOS S3 to reference the pins followed by a table
listing the EOS S3 pins. Due to the size of the board and components, the silkscreen is printed on the back of the
board. You can flip over the board reference the pin name and its respective function as well.
