Board: NXP IMXRT1050-EVKB
-------------------------

The tables below list the device configuration for this board. The board layer for the NXP IMXRT1050-EVKB is using the software component `::Board Support: SDK Project Template: project_template (Variant: evkbimxrt1050)` from `NXP.EVKB-IMXRT1050_BSP.13.1.0` pack.

The heap/stack setup and the CMSIS-Driver assignment is in configuration files of related software components.

The example project can be re-configured to work on custom hardware. Refer to ["Configuring Example Projects with MCUXpresso Config Tools"](https://github.com/MDK-Packs/Documentation/tree/master/Using_MCUXpresso) for information.
