PCA9957HN-ARD evaluation board
pins on the PCA9957HD-ARD board and the 2 x 20 connector pins on the i.MX 8M Mini
LPCCR4 EVK board.
Figure 8 shows how these three boards are connected. This configuration consists of:
• One i.MX 8M Mini LPDDR4 EVK board
•
One PCA9957HN-ARD board
• One IMX8MMINI-IARD interposer board
• One USB-C cable
• One USB Micro-B cable
To power-up and operate the setup, the USB-C cable for power must be connected to
PORT 2 of the EVK board. The power switch SW101 on the EVK board must be set to
the ON position to power-up the setup. Data communication is achieved by routing a
USB Micro-B cable from a USB port on the PC to the debug port (J901) on the EVK.
Attach the daughter board by plugging the PCA9957HN-ARD board into the Arduino
connector of the IMX8MMINI-IARD interposer and then plugging the IMX8MMINI-IARD
interposer into the expansion connector (J1003) located on the i.MX8MMINI EVK board.
(See Figure 8 for the location of all referenced connectors and switches.)
