Flash Memory:
Options for 0GB, 8GB, 16GB, or 32GB eMMC Flash memory (depending on model)

Peak eMMC bandwidth 100MBytes/s (four times faster than previous Compute modules)

 

Radio:
Option for Fully certified radio module with :

  • 2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac wireless
  • Bluetooth 5.0, BLE
  • On board electronic switch to select between external or PCB trace antenna

 

Video:

  • 1 x PCIe 1-lane Host, Gen 2 ( 5Gbps )
  • 1 x USB 2.0 port ( highspeed )

MIPI DSI:

  • 1 x 2-lane MIPI DSI display port
  • 1 x 4-lane MIPI DSI display port

 

MIPI CSI-2:

1 x 2-lane MIPI CSI camera port

1 x 4-lane MIPI DSI camera port

 

1 x SDIO 2.0 (CM4Lite only)

Single +5v PSU input.

28x user GPIO supporting either 3.3v or 1.8v signalling and various interface options:

  • Up to 6x UART
  • Up to 6x I2C
  • Up to 5x SPI
  • 1x SDIO interface
  • 1x DPI (Parallel RGB Display)
  • 1x PCM
  • Up to 2x PWM channels
  • Up to 3x GPCLK outputs

 

All of these features can be broken out on the Raspberry Pi Compute Module 4 IO board.

New connectors
image

The new connectors on the underside of the Raspberry Pi CM4 are designed to help you make the Raspberry Pi the heart of your embedded project.

 

32 variants - A Choice of Ram and eMMC Flash Memory

image

With four RAM options, four Flash options, and optional wireless connectivity, There are a total of 32 variants, with prices ranging from $25 (for the 1GB RAM, Lite, no wireless variant) to $90 (for the 8GB RAM, 32GB Flash, wireless variant). The 1GB RAM and no wireless variants keep the same price points ($25, $30, $35, and $40) as their Compute Module 3+ equivalents: once again, they have managed to pack a lot more performance into the platform without increasing the price.

    Nice! Much better size and connector : )

    There's so many variants of the compute modules, it's getting hard to track prices and availability (i.e. how many years guaranteed availability) each one has, since not all applications will need the CM4. Too many choices : )

     

    But interestingly, perhaps CM4 might save costs overall, since it's smaller, and now (finally) it appears to contain on-board Ethernet PHY chip so no need to cost that in separately. So that may complicate a feature/pricing comparison too.

     

    EDIT: just noticed they're using 0.4mm pitch connectors..  not insurmountable, but they had the space for larger connectors on the underside perhaps. They are using near-similar connectors that Intel Edison used.. so a bit of a pain, some accuracy is needed.
