Chapter 2. Hardware
This chapter describes the hardware features of the PIC32MK General Purpose (GP)
Development Board.
2.1
HARDWARE FEATURES
The following key features of the development board are presented in the order given
in
Section 1.3 “Kit Functionality and Features”
. See
Figure 1-2
for their locations on
the development board.
2.1.1
Processor Support
The development board kit is designed with a permanently mounted (i.e., soldered) processor,
PIC32MK1024GPE100.
2.1.2
Power Supply
Power is supplied to the development board by a USB bus power, which is connected
to the USB debug connector J12.
One green LED (D6) is provided to indicate the PIC32 device is powered up.
2.1.3
Debug USB Connectivity
The development board includes a PIC24FJ256GB106 USB microcontroller that
provides debugger connectivity over USB. 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.
If MPLAB REAL ICE or MPLAB ICD 3 is used with the starter kit, disconnect the on-
board debugger from the PIC32 device by removing the jumper J11. When the
on-board debugger is required, replace the jumper J11. When the jumper JP2 is
installed, pin 1 must be connected to pin 3 and pin 2 must be connected to pin 4.
2.1.4
PIC32 USB Connectivity
There are three possible ways to connect to the PIC32 USB microcontroller:
• Host mode – Connect the device to the Type-A connector J14, which is located on
the top of the starter kit. If using the Debug USB port to power the Host port, install
the jumper JP1 to short the back-power prevention diode. A maximum of ~400 mA
can be supplied from the Debug USB port to the Host port using this method. If
the full 500 mA supply is needed, an external supply must be connected to the
application board, and jumper J28 must be removed to prevent back-powering the
Debug USB port.
