Get Started

The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.

This page will guide you through the process of setting up and using the PCT2075DP- ARD evaluation board.

p>PCT2075DP-ARD evaluation board is designed and built as a daughter board able to work with a mother board equipped with an Arduino port. The board is built to be fully compatible with the following NXP evaluation boards:

The required firmware for the EVK boards is available for download at NXP site. Before starting a pair EVK – PCT2075DP-ARD, the EVK motherboard must be programmed with the corresponding firmware package. Additionally, a GUI application (Windows 10) is available for download from the same NXP site, allowing rapid testing and operation of PCT2075DP-ARD daughter board through one of the EVKs.

The GUI application is common for all three EVKs. For details regarding installation of the EVK firmware and GUI host software, see UM11581, Arduino shields GUI and firmware installation manual.

Once the software is installed, the first step is to select the correct combination of EVK/daughter board from the GUI, and then the board can be controlled from the GUI interface.

3.1 Additional Software Support

Refer to UM11580, PCT2075DP-ARD evaluation board and UM11581, Arduino shields GUI and firmware installation manual for additional software details.

4.1 Using PCT2075DP-ARD with MIMXRT1050-EVK Board

Figure 1 shows the required hardware for operation of the PCT2075DP-ARD daughter board with MIMXRT1050-EVK.

  • One MIMXRT1050-EVK board
  • One PCT2075DP-ARD daughter board
  • One USB-A / USB Micro-B cable
  • PC with Windows 10 operating system

The MIMXRT1050-EVK motherboard can be powered through three different connectors: using an external 5.0 V DC power supply, connected to J2 barrel power connector, directly from an USB port through J9 USB Micro-B connector (J9), or from the same USB port through J28 connector. J28 can be used as a debug connector, therefore using J28, through the same USB cable, the EVK can be powered and in the same time linked to PC for data exchange. The older USB ports (from PC) are not able to deliver the necessary current (500 mA), before establishing the communication, use an external power supply (connected to J2). From J1 (see Figure 1), the user can select the power configuration for the mother board. For more details, see i.MX RT1050 Evaluation Kit.

Figure 1. PCT2075DP-ARD daughter board and MIMRTX1050-EVK board

To configure the hardware and workstation, complete the following procedure:

  1. Configure the suitable power configuration of EVK (J1). If the user is using J28 for power supply, the J1 jumper is placed in position 5-6. If the user uses an external power supply (connected to J2), the jumper J1 is placed in position 1-2
  2. Insert the PCT2075DP-ARD daughter card on the Arduino port of the EVK (see Figure 1)
  3. Connect the MIMXRT1050-EVK board using J28 connector to USB port of the computer
  4. Install the IMXRT1050 target firmware (download from NXP site and see UM11581 for step-by-step instructions)
  5. Install GUI application on PC (see UM11581, Arduino shields GUI and firmware installation manual)
  6. Open the GUI application to operate the device from the PC

4.2 Using PCT2075DP-ARD with LPC55S69-EVK Board

Figure 3 shows the required hardware for operation of the PCT2075DP-ARD and LPC55S69-EVK board.

  • One LPC55S69-EVK board
  • One PCT2075DP-ARD daughter board
  • One USB-A / USB Micro-B cable
  • PC with Windows 10 operating system

The LPC55S69-EVK board is equipped with four USB Micro-B connectors: P5, P6, P9, and P10. The board can be powered through any USB port. Using P6 USB connector to connect the board to the PC, the bring-up operation is simplified because P6 is designated for debug and the USB cable will accomplish two tasks in the same time: powering the board, and data link between the EVK board and PC. For more details, see LPCXpresso55S69 Development Board.

Figure 3. PCT2075DP-ARD daughter board and LPC55S68-EVK mother board

To configure the hardware and workstation, complete the following procedure:

  1. Insert the PCT2075DP-ARD daughter card to P16 – P19 connectors located on LPC55S69-EVK development board (see the marked pins of P16 – P19, Figure 3)
  2. Connect the development board using port P6 USB port of PC
  3. Install the LPCXpresso55S69 target firmware (download from NXP site and see UM11581 for step-by-step instructions)
  4. Install GUI application on PC (see UM11581, Arduino shields GUI and firmware installation manual)
  5. Open the GUI application to operate the device from the PC

4.3 Using PCT2075DP-ARD with 8MMINILPD4-EVK Board

If 8MMINILPD4-EVK board is used for PCT2075DP-ARD operation, a third board (IMX8MMINI-IARD interposer board) must be used, especially designed and built as EVK – daughter board interconnection. The 8MMINILPD4-EVK is not equipped with an Arduino port; instead it has a 2x20 pin expansion connector (J1003, see 8MMINILPD4- EVK user manual). J1003 is a multipurpose port, containing different digital I/O lines, including specialized I2C and SPI buses. Starting from the expansion connector pin chart, an Arduino port interposer board was developed.

Figure 5 shows, along with the EVK and daughter board, a third board is included in thesetup assembly. To power-up and operate the setup, it is also necessary to have one USB-C cable for power (see Figure 6), connected to Port 2 of the EVK board. The board is equipped with a power switch (SW101) which is positioned in ON position to power up the setup. Data communication is assured through a second (USB Micro-B) cable connected to PC and debug port of the EVK (J901).

To attach the daughter board to the EVK, it is necessary to use the IMX8MMINI-IARD interposer boards by plugging PCT2075DP-ARD to the Arduino connector of the interposer, and then the interposer to expansion connector (J1003), located on the i.MX8MMINI EVK board (see Figure 5). The user may find more details regarding power-up and operation of the setup assembly in 8MMINILPD4-EVK user manual and IMX8MMINI-IARD User Manual.

Figure 5. PCT2075DP-ARD daughter board, IMX8MINI-IARD interposer board, and 8MMINILPD4 board assembly

To configure the hardware and workstation, complete the following procedure:

  1. Insert the PCT2075DP-ARD on IMX8MMINI-IARD interposer board Arduino connectors (located on the top side)
  2. Attach the obtained assembly to EVK (plug J1 connector of IMX8MMINI-IARD, located on the bottom side into J1003 expansion board located on the top side of 8MMINILPD4-EVK board
  3. Power up the EVK board using an USB Type C cable attached to Port 2
  4. Connect the EVK to the PC, using an USB Micro-B cable, attached to J901 debug port
  5. Place SW101 in On position to power up the boards
  6. Install the MIMXRT1050 target firmware (download from NXP site and see UM11581 for step-by-step instructions)
  7. Install GUI application on PC
  8. Open the GUI application to operate the device from the PC

4.4 Using PCT2075DP-ARD With Another Arduino Device

The PCT2075DP-ARD daughter board can be operated with different EVK boards, which has an Arduino port. There are two options to connect the board: using other EVK equipped with an Arduino port, and an EVK without Arduino port.

In the first case, a firmware is developed according to PCT2075 specifications, and then the PCT2075DP-ARD daughter board is attached to the EVK to operate the board.

In the second case, using the pin chart of Arduino connectors, make the necessary electrical connections (for power, I2C- bus and control lines), and develop the desired firmware compliant with IC specifications. Use PCT2075 data sheet to read details about internal registers of PCT2075 and data exchange between internal controller and the EVK. Ensure that the electrical connections are accurate and avoid data conflicts on the signal lines in order to prevent IC damage.
