12. Pads
Most microcontroller pins are available for further connectivity via two 1x26 rows of connection
pads on both sides of the mikromedia board. They are designed to match additional shields,
such as Battery Boost shield, Gaming, PROTO shield and others. Pads with underlined silkscreen
markings have multiple functions (see the complete schematic for more information).
