This page provides information about the amount of flash memory and RAM that is required by the :ref:`zigbee_samples`, as well as stack memory requirements for main and zboss threads.
Use it to check if your application has enough space for a given configuration.
Values are provided for :ref:`ZBOSS libraries <zigbee_zboss>`.
Note
Samples were built using the available :ref:`zigbee_zboss`. Unless stated otherwise, the default :file:`prj.conf` was used.
RAM and flash memory requirement values differ depending on the programmed sample.
The following tables list memory requirement values for Zigbee samples.
Values are provided in kilobytes (KB).
n/a indicates that the sample with the given variant is not supported on the DK.

The following table lists stack memory requirement values for main and zboss threads.
These measurements were carried out with Zephyr's `Thread analyzer`_, using the following Kconfig options for configuration:
- For the stack memory size of the
mainthread -CONFIG_MAIN_STACK_SIZE - For the stack memory size of the
zbossthread -CONFIG_ZBOSS_DEFAULT_THREAD_STACK_SIZE
Values are provided in bytes (B).
