Hardware 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 VBUS power from the host. 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 VDC may optionally be connected through the J1, J3 100 mil connector to power an external circuit from the dsPIC33CK LDO. However, a maximum of 50 mA consumption is recommended. 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 VDC power is connected to the +3V3PK on the PKOB4 LDO, which can supply up to 500 mA. 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® X IDE, v5.05 or later, when the dsPIC33CK Curiosity Board is connected to 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. FIGURE 2-1: 2.4 dsPIC33CK CURIOSITY PKOB TOOL SELECTION 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®, Mac® and Linux® operating systems. Under 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. DS50002859A-page 14  2019 Microchip Technology Inc. 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 VREF, 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 VDD current path to measure the 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. 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.  2019 Microchip Technology Inc. DS50002859A-page 15 dsPIC33CK Curiosity Development Board User’s Guide 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 FC = 506 kHz. There is an on-board MCP6021 op amp to power the internal VREF for the three op amps with 1.65V (VDD/2) voltage reference. VREF_EXT can also be used from connector J2 by removing, R30, 75 Ohm, and moving it into the R31 place (default DNP). The RC filters have a cutoff frequency: EQUATION 2-1: 1 F c = --------------2RC where R is the resistance and C is the capacitor of the filter. Example: R = 56 Ohms and C = 5600 pF, then FC = 507509 [Hz] or 507 [kHz]. Rise/fall time, with a steady state of 10% to 90%, is proportional to the time constant:  = RC. EQUATION 2-2: t r = 2.197 For example: R = 56 Ohms and C = 5600 pF, then tr = 0.68 µs.
