• 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.”

2.1 POWERING THE BOARD

2.1.1 USB Power

This board is intended to be primarily powered from the USB Micro-B connector, J7.
The official “USB 2.0 Specification” restricts USB applications to consuming no more
than 500 mA of USB V

2.1.2 External Power

An external +5 VDC may optionally be connected through the J2, J4 100 mil connector,
and the 2-pin jumper should be moved from +5V USB to +5V external power on the J11
3-pin connector.

An external +3.3 V
connector to power an external circuit from the dsPIC33CK LDO. However, a maximum
of 50 mA consumption is recommended.

DC may optionally be connected through the J1, J3 100 mil

2.1.3 mikroBUS™ Power

An external +5 VDC may optionally be connected through the J2, J4 100 mil connector.
In this case, the 2-pin jumper should be moved from +5V USB to +5V external power
on the J11 3-pin connector. A maximum of 400 mA is recommended to be supplied to
the mikroBUS click boards™.

The mikroBUS +3.3 V
can supply up to 500 mA.

DC power is connected to the +3V3PK on the PKOB4 LDO, which

2.2 USING THE PROGRAMMED DEMO FIRMWARE

The development board comes programmed with some basic demo firmware, which
exercises several of the board hardware features. The demo project for the dsPIC33CK
Curiosity Development Board implements an RGB color mixing application. In the
demo, the potentiometer can be used to adjust each color channel intensity
independently, while the push buttons are used to select the channel to be adjusted.

The source code for the demo can be obtained from:

www.microchip.com/dspic33ckcuriosity

2.3 REPROGRAMMING AND DEBUGGING THE dsPIC33CK256MP508 DEVICE

The board has a PICkit™ On-Board (PKOB) programmer/debugger circuit, which can
be used to program and debug the dsPIC33CK256MP508 target device (U1).
Alternatively, an external programmer/debugger tool can be connected to the board via
the 6-pin in-line connector J8, using a male-male 100 mil pitch 6-pin header.

 2019 Microchip Technology Inc. DS50002859A-page 13

dsPIC33CK Curiosity Development Board User’s Guide

The PKOB circuit should automatically enumerate and be recognized by the
MPLAB
the host via the USB Micro-B connector, J7. No custom USB driver installation is
necessary as the PKOB circuit relies on standard OS provided Human Interface Device
(HID) drivers, and therefore, the driver installation should be fully automatic. When
plugged in, the PKOB programmer/debugger tool can be selected from the MPLAB X
project properties page by selecting the device under: Hardware Tools>Microchip
Kits>Starter Kits (PKOB)>Curiosity/Starter Kits (PKOB4), as shown in Figure 2-1.

2.4 USING THE USB-UART INTERFACE

The board is equipped with a USB-UART interface based around the MCP2221A chip.
The MCP2221A chip implements the standard Communication Device Class (CDC) –
Abstract Control Model (ACM) protocol, and therefore, can use standard USB drivers
that are provided with modern Windows
most operating systems, the USB driver installation will be fully automatic. Under cer­tain older operating systems, or if the device is attached to an older than Windows 10
machine without an active Internet connection, manual installation of the drivers may
be necessary. In this case, the driver package can be downloaded from:

www.microchip.com/mcp2221a

Details on how to access the serial port from Mac and Linux operating systems can also
be found in the associated collateral for the MCP2221A. Under Windows, after
successful USB driver installation, the device will appear as a “COMx” port object,
which standard serial terminal programs can open/read/write to and from.

2.5 CIRCUIT DETAILS

This section highlights some of the circuit elements and provides an explanation for
their intent and function.

2.5.1 Jumpers/Headers/Connectors

J1, J3 – These are populated 2x25-pin, 100 mil jumper headers, in which a power
module or any other custom designed board may optionally be inserted to access the
microcontroller’s digital pins. Use the triangle alignment mark on J1, pin 1 (underneath
V

REF, see Figure 1-1) to connect the dsPIC33CK Curiosity Development Board to other

boards.

J2, J4 – These are populated 2x25-pin, 100 mil jumper headers, in which a power
module or any other custom designed board may optionally be inserted to access the
microcontroller’s analog and digital pins.

J5, J6 – These are female headers that implement the mikroBUS Interfaces A and B,
which are used to attach hardware daughter boards to expand the functionality of the
development board.

J7 – This is a standard female USB Micro-B connector, which connects to the
MCP2221A USB-UART converter chip and the on-board MPLAB PKOB4
programmer/debugger. This USB interface has a data interface and supplies power to
the rest of the board, as well as to the mikroBUS A and B, up to 400 mA.

J8 – This is an unpopulated 6-pin staggered header interface that can optionally be
used to connect an external programmer/debugger to the target microcontroller, U1.
The J8 header connects to the debug port, PGx3. The holes are slightly staggered,
which provides some friction retention force without requiring physical soldering when
a straight male-male or right-angle male-male header is installed into J8.

J9 – This is an unpopulated 2-pin, 100 mil jumper header, which may optionally be used
to insert a current meter in series with the U1 V
microcontroller’s current consumption. In order to measure the U1 current, the trace
(NT1) on the bottom of the PCB, that shorts the two pins of J1, should be cut and a
2-pin jumper should be soldered into J9.

J10, J12 – These are populated 2x2-pin, 100 mil jumper headers, which may optionally
be used to insert GND_D of a power module or any other custom designed boards that
access the microcontroller’s analog and digital pins. Also, it has the purpose of a
mechanical key that will prevent reverse connection.

DD current path to measure the

2.5.2 User Interface (UI)

The dsPIC33CK Curiosity Board contains a User Interface (UI), easily accessible on
the right side (see Figure 1-1). The UI has the following elements:

• One RGB LED

• A 10K Potentiometer

• Three Push Buttons

• Two Debug Orange LEDs

Each element can be programed for any purpose to create the desired interaction
between the user and the board behavior.

2.5.3 ADC Op Amp Analog RC Section

The board contains three RC filter components for each individual ADC core of the
microcontroller, U1. They are identical; the only difference is that one connects to the
dedicated ADC Core 1, another to the dedicated ADC Core 0 and the third one to the
shared ADC core.

The default configuration is the internal op amp variant, in which all passive
components, R and C, are populated for the filter, feedback and bias circuits.

To use the external op amp, remove R59, R75 and R81 resistors and populate C24,
C25 and C26 with 5600 pF, 50V, 0603, COG resistors to enable an RC filter of
F

C = 506 kHz.

There is an on-board MCP6021 op amp to power the internal V
op amps with 1.65V (V
