This chapter provides a functional overview of the MPLAB Starter Kit for PIC18F, and 
identifies the major hardware components. Topics covered include:

• Application Functional Overview

• Programmer/Debugger Functional Overview

• Board Components

Figure 4-1 illustrates the main functions of the starter kit:

The application side of the starter kit is centered on the PIC18F46J50 microcontroller, 
which requires very little additional hardware to perform its tasks. The MPLAB Starter 
Kit for PIC18F comes preprogrammed with a MicroSD bootloader that has the ability to 
load, program and run precompiled applications from a MicroSD memory card to the 
device’s Flash program memory. The MicroSD bootloader uses substantial parts of the 
Microchip Memory Disk Drive file system. The precompiled demos use substantial 
parts of the Microchip USB Stack Library.

The applications accept user inputs from three sources: the capacitive touch pad, S1 
(A5), the acceleration sensor, U6 (A4), and the potentiometer, R24 (A7).
