6.3 Using the NTS0304EUK-ARD with an i.MX 8M Mini LPDDR4 EVK
board
When an i.MX 8M Mini LPDDR4 EVK board is used with the NTS0304EUK-ARD board, a
third board (IMX8MMINI-IARD interposer board) must be used, especially designed and
built as an EVK – daughterboard interconnection. The EVK board i.MX 8M Mini LPDDR4
is not equipped with an Arduino port; instead it has a 2 x 20 pin expansion connector
(J1003, see i.MX 8M Mini LPDDR4 EVK user manual). J1003 is a multipurpose port,
containing various digital I/O lines, including specialized I
2
C and SPI buses. Starting from
the expansion connector pin chart, an Arduino port interposer board was developed,
with the role of signal-to-signal bridge between the 2 x 20 connector pins on the i.MX
8M Mini LPDDR4 EVK and the mated connectors of the Arduino port present on the
NTS0304EUK-ARD daughterboard.
To operate the setup, along with the EVK and the daughterboard, 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 NTS0304EUK-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 NTS0304EUK-ARD to the Arduino connectors of the
IMX8MMINI-IARD interposer board first, and then the resulting assembly to the i.MX 8M
