Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

Introduction to Curiosity
1.3
POWER SOURCES
The Curiosity Development Board can be powered in one of three ways, depending on
its usage.
1.3.1
USB Connector (J2)
The USB connector (J2) will power the entire Curiosity Development Board. A shunt
jumper must be placed onto jumper J12 (Figure 1-2). The right two pins of J12 will
connect +5V from the USB connector J2. The left two pins of J12 will connect +3.3V
from the USB voltage regulator on the back side of the development board. With USB
power connected to J2, power LED D1 will always be ON to indicate that +3.3V is
available on the board.
1.3.2
9V External Power Supply (J15)
The 9V external power supply (J15) will also power the entire Curiosity Development
Board. A shunt jumper must be placed onto jumper J12 (Figure 1-2). The right two pins
of J12 will connect +5V from the on-board voltage regulator circuitry connected to
connector J15. The left two pins of J12 will connect +3.3V from the on-board voltage
regulator circuitry. With 9V external power connected to J15, power LED D1 will always
be ON to indicate that +3.3V is available on the board. Power LED D2 will only be ON
when power (+3.3V or +5V) is applied to VDD via a shunt jumper placed on J12.
1.3.3
Variable External Power Supply (TP3, TP4)
A variable external power supply connected to TP3 and TP4 will power the entire
Curiosity Development Board. A shunt jumper is not needed on J12, thus either +3.3V
or +5V can be directly applied via a variable external power supply to VDD.

CURIOSITY DEVELOPMENT BOARD
USER’S GUIDE
Chapter 2. Getting Started
The Curiosity Development Board must be used with MPLAB X Integrated
Development Environment (IDE), available free on Microchip's web site,
www.microchip.com. Use version v3.05 or later.
The Curiosity Development Board, through MPLAB X, is a low-voltage in-circuit
debugger, as well as a low-voltage programmer, for all supported devices. In-circuit
debugging allows the user to run, examine and modify programs for the supported
device embedded in the Curiosity hardware. This facilitates the debugging of firmware
and hardware concurrently. Use the Curiosity Development Board with MPLAB X IDE
to run, stop and single-step through programs –breakpoints can be set and the
processor can be reset. When the processor stops, the contents of the register are
available for examination and modification.
2.1
PROGRAMMING THE CURIOSITY DEVELOPMENT BOARD
After connecting the Curiosity Development Board to the computer using the on-board
USB connector (J2 on the back of the board), open the MPLAB X IDE. Then create a
new project or open an existing project. Click on the Project Properties icon located in
the project's Dashboard window (Figure 2-1). Alternatively, the Project Properties
window can be opened by clicking on File > Project Properties, or by right-clicking on
the project name in the Projects window and clicking Properties. (Figure 2-1).

DS40001804B-page 15
Curiosity Development Board User’s Guide
MPLAB X refers to the Curiosity Development Board as “Starter Kits (PKOB)”, with
“Curiosity” listed below. Click on Curiosity, the correct device and XC8 compiler
version being used, then click Apply (Figure 2-2). On the upper left hand corner of the
Properties window, click on Starter Kit (PKOB) (Figure 2-3). The window will change
to the Options for Starter Kit (PKOB) window (Figure 2-3).

Note:
When using the PKOB for programming, the Low Voltage Programming
(LVP) bit of the Configuration Word(s) must be set (LVP = ON or '1').
Select options category “Program Options” and then “Enable Low Voltage
Programming,” if it is not already selected. Click Apply, then OK (Figure 2-3). Once the
project is finished, the microcontroller is ready to be programmed. Simply click on the
Make and Program Device Main Project button and the device will be programmed
(Figure 2-4).

USER’S GUIDE
Chapter 3. Troubleshooting
This chapter discusses common operational issues and how to resolve them.
3.1
THE DEMO APPLICATION DOES NOT RUN
Curiosity Development Board must be plugged into a powered USB hub, computer, or
other USB host device. To run the application, ensure the conditions listed below are
met:
1. Start by plugging it into the USB device port, J2. LEDs D1 and D2 should light
when VBUS is detected.
2. If D1 is not lit, verify that the USB host side port is functional.
3. If D2 is not lit, verify that jumper J12 is connected to the proper device voltage.
3.2
THE MCU WILL NOT PROGRAM USING THE PKOB
The Curiosity Development Board's PICkit on board (PKOB) uses low-voltage
programming. The demo application code sets the Low Voltage Programming (LVP) bit
to a '1', allowing low-voltage programming.
1. When using custom firmware, the LVP bit must be set to '1' in the Configuration
Word. MPLAB X will not allow programming using the PKOB unless the bit is
properly configured.
2. When using a PIC microcontroller (one not included with the Curiosity
Development Board) that has already been programmed using high-voltage
programming and the LVP bit cleared (LVP = OFF or '0'), the device will not be
recognized and cannot be programmed using the PKOB. Reprogramming the
device can be achieved by one of the following two methods:
a) Connect a PICkit 3 Programmer to the Curiosity board, configuring MPLAB
to use the PICkit 3 as the programmer, and ensuring the LVP bit is set to '1'
in the Configuration Word. Reprogram the device.
b) Use an unprogrammed (blank) device and ensure the LVP bit is set to '1' in
the Configuration Word.
3.3
THE MCU WILL NOT PROGRAM USING THE PICkit 3
If the PIC device will not program using the PICkit 3, ensure that the 3.3/5V jumper
(J12) is removed.

CURIOSITY DEVELOPMENT BOARD
USER’S GUIDE
Appendix B. General Notes
B.1
POWER
When the Curiosity board is USB-powered though a 5V supply rather than a USB port
on a computer, MCLR is held in Reset for approximately five seconds.
B.2
RN4020 BLUETOOTH® LOW ENERGY (BLE) MODULE
1. The RN4020 Bluetooth Low Energy (BLE) module must be configured before
use. This can be achieved by either of the following methods:
a) Connecting the UART TX and RX lines to an external UART-to-USB bridge,
such as the MCP2200, and using a terminal program to communicate with
and program the BLE module
b) Writing custom firmware and programming the BLE module through the PIC
MCU.
2. The Wake_HW line (pin 15 of the RN4020) was not connected, but is now
recommended. This line must be connected for proper BLE functionality. See the
RN4020 Bluetooth® Low Energy Module Command Reference User’s Guide
(DS70005191) for more information.
B.3
CLICK OR RN4020 MODULES
Shared UART TX and RX lines supply connection to either the RN4020 BLE module or
a Click module (which uses UART for communication with the PIC MCU), but not both.
B.4
DEBUGGING MODE
During Debug mode, LED D5 is not available to the user. This was done to provide
out-of-the-box LED access to Microchip’s 8-pin MCUs. There are zero-ohm-resistors in
series that can be removed to allow connection to another pin, if desired.
B.5
ROUTING AND FLEXIBILITY
Pinouts to the various connections provide connectivity to many devices. With
zero-ohm-resistors in series to all connections, i.e., the mikroBUS™, TouchPad, and
LEDs, the board can be modified for many situations without cutting the printed circuit
board (PCB) traces.
