Hardware Description
2.1.7.3 Breadboard Connection
The breadboard adapter section of the board is a set of 98 holes on a 0.1 inch grid. Properly combined with a pair of right angle headers, the
entire Crypto Connected LaunchPad can be plugged directly into a standard 300 mil (0.3 inch) wide solder-less breadboard. The right angle
headers and breadboard are not provided with this kit. Suggested part numbers are Samtec TSW-149-09-L-S-RE and TSW-149-08-L-S-RA right
angle pin headers and Twin industries TW-E40-1020 solder-less breadboard. Samtec TSW-149-09-F-S-RE and TSW-149-09-F-S-RA may be
substituted.
A detailed explanation of how to install the headers is available on the TI LaunchPad Wiki or at
http://users.ece.utexas.edu/~valvano/EE345L/Labs/Fall2011/LM3S1968soldering.pdf .
Nearly all microcontroller signals are made available at the breadboard adapter holes (X11). These signals are grouped by function, where
possible. For example, all EPI signals are grouped on one side of the connector. Many of the analog signals are grouped near VREF, and UART,
SSI and I2C signals are grouped by peripheral to make expansion and customization simpler.
Table 2-3 and Table 2-4 show the GPIO pin and signal muxing for the X11 breadboard adapter pads.
