PCA9846PW-ARD evaluation board
To operate the setup, along with the EVK and the expansion board, a third board must be
included in the setup assembly.
shows the necessary boards and how these
boards are connected. The configuration consists of:
•
One i.MX 8M Mini LPDDR4 EVK board
•
One PCA9846PW-ARD expansion 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 PCA9846PW-ARD to the Arduino connectors of the
IMX8MMINI-IARD interposer board first, and 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 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

To configure and operate the setup, follow the below steps:
1. Insert the PCA9846PW-ARD onto the IMX8MMINI-IARD interposer board Arduino
