The Raspberry Pi Compute Module 4 represents a huge change for the Compute Module line. The biggest change being the move from the DDR2 SODIMM connector form factor to a high density connector on the bottom of the board.
The Raspberry Pi Compute Module 4 represents a huge change for the Compute Module line. The biggest change being the move from the DDR2 SODIMM connector form factor to a high density connector on the bottom of the board. But true to the line, the Compute Module 4 packs all the best features of the Raspberry Pi Model B 4 into a more favorable form-factor for embedded or OEM applications.
The board includes the same 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU on the Raspberry Pi 4 and is capable of 4k Video via dual HDMI interfaces. It has a single-lane PCI 2.0 express interface with dual MIPI DSI display and CSI-2 camera interfaces. For the first time, wireless capability is offered on the Compute Module line in the form of an optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0 radio. The board supports Gigabit Ethernet PHY with IEEE 1588 support and has 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI.
This model has 4GB of LPDDR4-3200 SDRAM and 16GB on-board Flash storage along with the wireless capability (2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0).
As with the Compute Module 3+, the Compute Module 4 is available with a choice of eMMC storage densities: 0GB (Lite); 8GB; 16GB; and 32GB along with a choice of DRAM densities: 1GB; 2GB; 4GB; and 8GB. As a result, there are 32 distinct variants of the product, each with its own part number. If you do not see the combination you’re looking for on our site yet, please email support@sparkfun.com.
