Compute Module 4

Compute Module 4

cm4-wl-1-short.jpg

A Step Change in Performance

Built on the same 64-bit quad-core BCM2711 application processor as Raspberry Pi 4, the Compute Module 4 delivers a step change in performance over its predecessors: faster CPU cores, better multimedia, more interfacing capabilities, and, for the first time, a choice of RAM densities and a wireless connectivity option. A new Compute Module 4 IO Board supports the platform, and a certified external antenna kit is available to increase the on-board wireless performance.

New, More Compact Form Factor

Compute Module 4 introduces a brand new form factor, and a compatibility break with earlier Compute Modules. Where previous modules adopted the JEDEC DDR2 SODIMM mechanical standard, with I/O signals on an edge connector, we now bring I/O signals to two high-density perpendicular connectors (one for power and low-speed interfaces, and one for high-speed interfaces). This significantly reduces the overall footprint of the module on its carrier board, letting you achieve smaller form factors for your products.

Compute Module 4 Feature List

  • VideoCore VI graphics, supporting OpenGL ES 3.x
  • 4Kp60 hardware decode of H.265 (HEVC) video
  • 1080p60 hardware decode, and 1080p30 hardware encode of H.264 (AVC) video
  • Dual HDMI interfaces, at resolutions up to 4K
  • Single-lane PCI Express 2.0 interface
  • Dual MIPI DSI display, and dual MIPI CSI-2 camera interfaces
  • Gigabit Ethernet PHY with IEEE 1588 support
  • 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI
  • 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM Densities
  • Optional 8GB, 16GB or 32GB eMMC Flash storage
  • Optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0

The choice of RAM densities, storage options, and wireless option create 32 variations of the Compute Module 4. These are listed below in a reference table with links to each product variation.

Compute Module 4 IO Board

Like the IO boards for earlier Compute Module products, this 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.

io-board-1-short.jpg

In addition to serving as a development platform and reference design, the IO board is a finished product in its own right: if you require a Raspberry Pi that supports a wider range of input voltages, has all its major connectors in a single plane, or allows you to attach your own PCI Express devices, then Compute Module 4 with the IO Board does what you need.

See the IO Board product page for complete details.
