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 NAFExx388- EVB board.

3. Configure Hardware
3.1 Configure the Hardware
The NAFExx388 evaluation kit includes the NAFExx388 evaluation board, an OM13098 (LPC54628) evaluation board, and a USB cable.
To set up the hardware, do the following:
- Firmly connect the NAFExx388 (AFE) evaluation board to the LPC54628 (microcontroller) evaluation board using the Arduino connectors.
- To connect both boards, slide
J15,J18,J19, andJ22male connectors at the bottom side of the NAFExx388 (AFE) evaluation board into the appropriate female connectors on the LPC54628 (microcontroller) evaluation board. - Apply AVDD/DVDD = 3.75 V on
J9, HVDD = +15.4 V onJ10, and HVSS = -15.4 V onJ11banana jack connectors and turn on the power supply. - Connect USB to µUSB cable between USB port of the computer and
J2(µ USB) port of LPC54628 evaluation board.
