• Description
• 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 1GB of LPDDR4-3200 SDRAM and no on-board Flash storage.
• 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
