PCA9959HN-ARD evaluation board
•
One USB-A / USB Micro-B cable
•
A PC with Windows 10 operating system
It is recommended to attach the PCA9959HN-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 a USB port on the PC to debug port (J901) on the EVK (see
and
).
For more details regarding the power-up and operation of the setup assembly, see
i.MX
8M Mini LPDDR4 EVK Board Hardware User's Guide
(IMX8MMEVKHUG.pdf), and
IMX8MMINI-IARD User Manual. The files can be downloaded from
Figure 10. PCA9959HN-ARD daughter board, IMX8MMINI-IARD interposer board, and
8MMINILPD4-EVK board assembly
To configure the hardware and workstation, complete the following procedure:
1. Insert the PCA9959HN-ARD onto the IMX8MMINI-IARD interposer board Arduino
connectors (located on the top side).
2. Attach IMX8MMINI-IARD connector 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
3. Power-up the EVK board using an USB Type C cable attached to Port 2.
4. Connect the EVK to the PC using a USB Micro-B cable attached to J901 debug port.
