Chapter 2. Hardware

This chapter describes the hardware features of the starter kit.

2.1

HARDWARE FEATURES

The key features of the PIC32 USB Starter Kit III are listed below. They are presented

in the same order as described in Section 1.2 “PIC32 Functionality and Features”.

You can refer to Figure 1-1 for their locations on the board.

2.1.1

Processor Support

The PIC32 USB Starter Kit III is designed with a permanently mounted (i.e., soldered)

PIC32MX470F512L processor.

2.1.2

Power Supply

There are two ways to supply power to the PIC32 USB Starter Kit III:

• USB bus power connected to the USB debug connector, J3

• An external application board with a regulated DC power supply that provides +5V

can be connected to the J1 application board connector that is provided on the

bottom side of the board

One green LED, PWR (D7), is provided to indicate the PIC32 microcontroller is

powered.

2.1.3

Debug USB Connectivity

The PIC32 USB Starter Kit III includes a PIC24FJ256GB106 that provides debugger

connectivity over USB PKOB. The PIC24FJ256GB106 is hard-wired to the PIC32

device to provide protocol translation through the I/O pins of the PIC24FJ256GB106 to

the ICSP™ pins of the PIC32 device.

The PIC32 USB Starter Kit III currently uses the ICSP pins of the PIC32 device for

programming and debugging.

2.1.4

PIC32 USB Connectivity

The following are three possible ways to connect to the PIC32MX470F512L:

• HOST mode – Connect the device to the Type A connector J5, which is located on

the top side of the starter kit. If using the Debug USB port to power the Host port,

install jumper JP1 to short the back-power prevention diode. Note that a maximum

of ~400 mA can be supplied from the Debug USB port to the Host port using this

method. If full 500 mA supply is needed, an external supply must be connected to

the application board, and the jumper JP1 must be removed to prevent back-

powering the Debug USB port.
