PCAL6416AEV-ARD evaluation board
on the i.MX 8M Mini LPDDR4 EVK and the mated connectors of the Arduino port present
on the PCAL6416AEV-ARD daughter board.
To operate the setup, along with the EVK and the daughter board, a third board must be
included in the setup assembly. Figure 8 shows the necessary boards and how these
boards are connected. The configuration consists of:
• One i.MX 8M Mini LPDDR4 EVK board
•
One PCAL6416AEV-ARD daughter board
• One IMX8MMINI-IARD interposer board
• One USB-A / USB-C cable
• One USB-A / USB Micro-B cable
•
A PC with Windows 10 operating system
It is recommended to attach the PCAL6416AEV-ARD to the Arduino connectors of the
IMX8MMINI-IARD interposer board first, and then the resulting assembly to the i.MX 8M
Mini LPDDR4 EVK. This can be done by plugging J1 connector located on the interposer
board to J1003 connector on the EVK.
To power-up the EVK, a USB-C type cable connected to PORT 2 of the EVK is used.
The power switch SW101 on the EVK board must be set to ON position to power-up the
setup. Data communication is achieved by routing a separate USB (Micro-B type) cable
from an USB port on the PC to debug port (J901) on the EVK (see Figure 8 and Figure 9 .
The user may find details regarding power-up and operation of the setup assembly in
8MMINILPDDR4-EVK user manual and IMX8MMINI-IARD User Manual. The files can be
downloaded from www.nxp.com/ .
