7 Configuring the hardware
The FRDMDUALK3664EVB is configured as a shield board for the S32K3x4EVB-Q172
board. It can also be used in a standalone configuration. For other configurations, check
mechanical and electrical fit or use, for example, a breadboard design.
7.1 S32K3x4EVB-Q172 board configuration
The FRDMDUALK3664EVB is configured for the S32K3x4EVB-Q172 board by default.
Ensure that the S32K3x4EVB is configured correctly before connecting both boards
together.
lists the relevant S32K3x4EVB-Q172 configurations required with the
FRDMDUALK3664EVB. All other settings should use the default settings. For further
details, consult the S32K3x4EVB-Q172 board user manual
.

Table 12. S32K3x4EVB-Q172 recommended setting
When both boards are connected, the SPI and other signals are directly connected with
suitable MCU pins. Power is supplied to the FRDMDUALK3664EVB through the 5.0 V
from the S32K3x4EVB.
