### Partition Table ### Partition Table
It is not required to set a custom partition table. Per default the IDF will select `Single factory app, no OTA` and the firmware will create a partition for SPIFFS automatically which fills the remaining flash space. IDF's default partition table `Single factory app, no OTA` does not provide enough room for a firmware including large modules like e.g. `http` or `sodium`. To enable full feature sets, NodeMCU uses a custom partition table from `components/platform/partitions.csv` which allocates ~1.5 MB for the firmware image. During first boot, the firmware creates an additional partition for SPIFFS in the remaining flash space.
There is a template partition table available in `components/platform/partitions-2MB.csv` locates the SPIFFS partition at a fixed location. The file can be used as a template for custom partition tables with menuconfig: For 2MB flash modules an alternative partition table available as `components/platform/partitions-2MB.csv`. It restricts the SPIFFS partition to ~448 kB and can be used with menuconfig:
