Preparing the CryptoCape
In order to make the CryptoCape more
hackable
, we need to populate the pads attached to
the I/O signals with male headers. This will allow us to connect various external compon-
ents. While you could directly solder to the pads, it's best if you solder a male 0.1" pin,
which will allow you to easily connect a female terminated wire for your project, which
can then be reused.
A fully populated CryptoCape will look like the following image. A strip of breakaway
headers of 31 pins or more will be enough to populate each pad. Technically, you don't
need to populate the EEPROM write protect pads unless you want to write to the
EEPROM. However, if you overwrite the EEPROM cape information, the BBB might not
load the correct drivers.
