    6.3 Using the PCA9846PW-ARD with an i.MX 8M Mini LPDDR4 EVK board When an i.MX 8M Mini LPDDR4 EVK board is used with the PCA9846PW-ARD board, a third board (IMX8MMINI-IARD interposer board) must be used, especially designed and built as EVK-expansion board interconnection. The EVK board i.MX 8M Mini LPDDR4 is not equipped with an Arduino port.
  • Page 19 • 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.

    6.4 Using PCA9846PW-ARD with another device The PCA9846PW-ARD expansion board can be operated with other EVK board, which has an Arduino port. There are two options to connect the board. Use another EVK equipped with an Arduino port, or an EVK without Arduino port. In the first case, use a firmware developed with PCA9846A specifications and attach PCA9846PW-ARD expansion board to the EVK to operate the board.
