CURIOSITY DEVELOPMENT BOARD
USER’S GUIDEChapter 1. Introduction to Curiosity
®
The Curiosity Development Board supports Microchip’s 8-, 14- and 20-pin 8-bit PIC MCUs. Dual-row expansion headers on either side of the socket offer flexibility of connectivity to all pins on the PIC MCUs. This board provides flexibility for experimentation through an application header with ground (GND) and supply voltage (VDD) connections. It also includes a set of indication LEDs, mTouch® button and push button switches, and a variable potentiometer. Additionally, it features a Bluetooth® low-energy footprint and a mikroBUS™ footprint to accommodate a variety of plug-in Click board™ sensors that can be used in application development.1.1 CURIOSITY DEVELOPMENT BOARD KIT CONTENTSThe Curiosity Development Board kit contains the following:

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.
2015-2019 Microchip Technology Inc. DS40001804C-page 10
CURIOSITY DEVELOPMENT BOARD
USER’S GUIDEChapter 2. Getting Started
The Curiosity Development Board must be used with MPLAB X Integrated Development Environment (IDE), available free on Microchip’s website, 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).
FIGURE 2-1: SELECTING THE CURIOSITY DEVELOPMENT BOARD IN THE MPLAB® X IDE
2015-2019 Microchip Technology Inc. DS40001804C-page 11
Getting Started
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).
FIGURE 2-2: CURIOSITY DEVELOPMENT BOARD CONFIGURATION
FIGURE 2-3: PROGRAM OPTIONS FOR STARTER KIT (PKOB)
2015-2019 Microchip Technology Inc. DS40001804C-page 12
Getting Started
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).
FIGURE 2-4: PROGRAMMING THE DEVICE ON THE CURIOSITY DEVELOPMENT BOARD
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’).

CURIOSITY DEVELOPMENT BOARD
USER’S GUIDEChapter 3. Troubleshooting
This chapter discusses common operational issues and how to resolve them.
3.1 THE DEMO APPLICATION DOES NOT RUN
The Curiosity Development Board must be plugged into a powered USB hub, com-puter, 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 GUIDEAppendix B. General Notes
B.1 POWER
When the Curiosity board is USB-powered through 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.
