Figure 2-1 shows a simplified circuit for the MCP42XX PICtail Plus Daughter Board. 
The layout of the board is shown in Figure 2-3. This board can be operated with either 
a PICDEM board with a PICtail Plus header or the PICkit Serial Analyzer. The 
MCP42XX PICtail Plus Daughter Board kit comes with firmware for the Explorer 16 
Starter Kit (DV164033). The layout of this board is shown in Figure 2-5. 

The MCP42XX PICtail Plus Daughter Board supports the following Microchip Digital 
Potentiometer devices; which allows demonstration of all MCP42XX devices 

• MCP42X1
