2.1.6.3 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 Ethernet LaunchPad development kit can be plugged directly into a standard 300-mil (0.3-in) wide solderless 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 solderless breadboard. Samtec TSW-149-09- F-S-RE and TSW-149-09-F-S-RA may be substituted.

Most microcontroller signals are made available at the breadboard adapter holes (J10). 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 4 and Table 5 list the GPIO pin and signal muxing for the X11 breadboard adapter pads.
