PCAL6524EV-ARD evaluation board
2. Attach IMXMMINI-IARD connector plug 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 an USB Micro-B cable, attached to J901 debug
port;
5. Place SW101 in ON position to power-up the boards;
6. Install the MIMXRT1050 target firmware (download
and firmware installation manual
7. Install GUI application on the PC (see the instruction file referred in the above step);
8. Open the GUI application to operate the device from the PC. For details regarding
GUI operation see

6.4 Using PCAL6524EV-ARD with another device
The PCAL6524EV-ARD daughterboard can be operated with other EVK board, which
has an Arduino port. There are two options to connect the board: using other EVK
equipped with an Arduino port, and an EVK without Arduino port. In the first case, a
firmware shall be developed according with PCAL6524EV specifications, and then
simply attach PCAL6524EV-ARD daughterboard to the EVK, to operate the board. In the
second case, using the pin chart of Arduino connectors (
), make the necessary
electrical connections (for power, I
2
C-bus and control lines), and develop the desired
firmware, assuring that is compliant with IC specifications. Use PCAL6524 datasheet to
read details about internal registers of the DUT IC and data exchange between internal
controller and the EVK. Assure for correct electrical connections and avoid data conflicts
on the signal lines, to prevent IC damage.
