7.3 Using the PCA9957HN-ARD with an I.MX 8M Mini LPDDR4 EVK board
When an i.MX 8M Mini LPDDR4 EVK board is used with the PCA9957HN-ARD board,
a specially designed EVK daughter board—the IMX8MMINI-IARD board—must be
mounted as an interposer between the i.MX 8M Mini EVK board and the PCA9557HN-
ARD. This is because the i.MX 8M Mini LPDDR4 uses a 2 x 20-pin expansion connector
(J1003) instead of an Arduino connector.
Connector J1003 on the i.MX 8M Mini LPDDR4 EVK board is a multipurpose port
containing digital I/O lines, including specialized I
2
C and SPI buses. The IMX8MMINI-
IARD interposer serves as a signal-to-signal bridge between the Arduino connector
