Connector Summary
Refer to Figure 2-2. Little Board P6d Connector and Jumper Locations for the locations of the
connectors (J1 – J21) and configuration jumpers (W1 – W9). Table 2-1 summarizes the use of the
I/O connectors.
Each interface is described in its own section, showing connector pinouts, signal definitions,
required mating connectors, and configuration jumper options.
Many of the connectors have a key pin removed. This allows you to block the corresponding cable
connector socket to help prevent improper assembly. Table 2-1 indicates which pins are key pins.
