The power of the Raspberry Pi 4 in a compact form factor for deeply embedded applications!

The Raspberry Pi Compute Module 4 (CM4) harnesses the compute power of the popular Raspberry Pi 4 Model B, bringing it to a smaller form factor suitable for integration into products.

Key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K, hardware video decode at up to 4Kp60, up to 8GB of RAM, Gigabit Ethernet, USB 2.0, dual camera interfaces and PCIe Gen 2 x1 interface.

CM4 IO board, accessories and essentials are available in our dedicated Raspberry Pi Compute Module section!

CM4 Variations

The Compute Module 4 is available in many different variations to suit every project or product design (select variant options before adding to cart).

Customers can now choose a combination of the following:

  • Amount of onboard eMMC Storage: Lite/8GB/16GB/32GB
  • Amount of RAM: 1GB/2GB/4GB/8GB
  • Wireless / No Wireless

Please note: not all variations will be available initially. Please select 'notify me' to register for stock alerts.

New Optional IO Board

The optional Raspberry Pi 4 Compute Module 4 IO board breaks out all the interfaces from the Compute Module to standard connectors, providing a ready-made development platform and a starting point for your own designs.

Great for hardware developers, designers or even curious makers and tinkerers!

Note: IO board not included with CM$

Optional Wireless

The optional dual-band 2.4/5.0GHz wireless LAN and Bluetooth 5.0 have modular compliance certification. This allows the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market. Either the onboard antenna or an external antenna kit (coming soon) can be used.

The Compute Module 4 has optional onboard eMMC of 8GB, 16GB or 32GB (select version above).
