PIC32 FUNCTIONALITY AND FEATURES

Representations of the layout of the PIC32 USB Starter Kit III are shown in Figure 1-1

and Figure 1-2.

The top assembly of the board includes these key features, as indicated in Figure 1-1:

PIC32MX470F512L 32-bit microcontroller (U1).

Green power indicator LED (D7).

On-board crystal (Y1) for precision microcontroller clocking (8 MHz).

USB Type mini-B receptacle for on-board debugger communications (J3).

Green PICkit™ On-board (PKOB) debug indicator LED (D6).

Three push button switches, SW1, SW2, and SW3, for user-defined inputs (S1,

S2, S3).

Three user-defined indicator LEDs, LED1, LED2, and LED3 (D3, D4, D5).

USB Type A receptacle for PIC32 host-based applications (J5).

HOST mode power jumper (JP1).

10. Regulated +3.3V power supply for powering the starter kit via USB or expansion

board (U3).

Note:

When running USB device applications, open the jumper JP1 to prevent

possibly back-feeding voltage onto the VBUS from one port on the host to

another (or from one host to another).
