FIGURE 1-1: EXPLORER 8 DEVELOPMENT BOARD
1.4 ON-BOARD JUMPER CONFIGURATIONS
The Explorer 8 Development Board allows the user to connect or disconnect
components from PIC
MCU pins or from other on-board components through
associated jumpers. Table 1-1 and Figure 1-2 provide details and examples for these
connections.
