PCAL6534EV-ARD evaluation board
To operate the setup, along with the EVK and the daughterboard, a third board must be
included in the setup assembly. Figure 9 shows the necessary boards and how these
boards are connected. The configuration consists of:
• One i.MX 8M Mini LPDDR4 EVK board
•
One PCAL6534EV-ARD daughterboard
• 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 PCAL6534EV-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, an 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 9 and
Figure 10 ).
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/ .

LPDDR4 EVK, before starting
To configure and operate the setup, follow the below steps:
1. Insert the PCAL6534EV-ARD onto the IMX8MMINI-IARD interposer board Arduino
connectors (located on the top side)
2. Attach IMXMMINI-IARD connector plug J1 (located on the bottom of the board) into
J1003 expansion board located on the top side of i.MX 8M Mini LPDDR4 EVK (see
Figure 9 )
