Yes, Raspberry Compute module 4 and 4s come with the eMMC, it is the onboard storage that removes the hassle of using the SD card for Raspberry Pi. So, if you are interested in further to more about the compute module 4 and 4S and eMMC then have a thorough look at this guide.
What is eMMC?
The full form of eMMC is an embedded Multimedia Card and from its full form you can clearly understand that it is a storage system that is embedded on the PCBs. This storage is primarily designed for portable devices like Raspberry Pi and cell phones and tablets, these storage chips act as an alternative to the micro-SD cards used for storage.
Does Raspberry Pi have eMMC
As mentioned above, Raspberry Pi compute module 4 comes with the feature of having an embedded multimedia card with the storage options from 8GB to 32 GB. Since the compute module 4 and 4S is designed for industrial applications, the Raspberry Pi foundation found it necessary to have its own built-in storage system. If you are further interested to know more about the Compute Module 4 and 4S then see the table below that shows the specification of Raspberry Pi compute module 4 and 4S:
| Specifications | Compute module 4 | Compute module 4S |
| Processor | ARM (V8) 64-bit quad core 1.5GHz | ARM (V8) 64-bit quad core 1.5GHz |
| RAM | From 1GB to 8GB depending on variant | 1GB |
| Connectivity | Bluetooth 5.0, 2.5 GHz and 5GHz IEEE 802.11 wireless | No Bluetooth and wireless |
| Ports | 28 GPIOs, 1x USB 2.0, PCIe interface, 2x HDMI , 4-laneCSI camera interface, 2-lane display interface, 4-lane DSI display interface, 2-lane CSI camera interface | 1x USB 2.0, 46 GPIOs, 1xSDIO 2.0, 1xHDMI 2.0, 4-lane CSI camera interface, 2-lane DSI display interface, 4-lane DSI display interface, 2-lane CSI camera interface |
| Graphics | Open GL 3.0 | Open GL 3.0 |
| Storage | 8GB, 16GB or 32GB for variants with eMMC | 8GB, 16GB or 32GB for variants with eMMC |
| Form Factor | 55 mm × 40 mm | 67.6mm × 31.0mm |
Conclusion
Having a built-in storage system makes it easy to operate the Raspberry Pi boards, but unfortunately not all boards have a built-in storage system. The storage system that is mainly used for such devices is the eMMC that is an embedded multimedia card and in Raspberry Pi this comes with the storage options of 8 GB, 16 GB and 32 GB. The compute module 4 and 4s comes with the option of eMMC and both these boards fall in the category of raspberry Pi board specifically designed for industrial applications.
