Product Description

Raspberry Pi Compute Module 4 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. 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 can be used. Compute Module 4 has optional onboard eMMC of 8GB, 16GB or 32GB.

FAQ

1.Do I need a heatsink when I design a system based on Raspberry Pi Compute Module 4?

A: Yes. You have to consider the heat of Compute Module 4 in your design because there are multiple hot components on Compute Module 4- CPU, PMU Chip and Wireless Module. If your system operate at 1.5GHz, full load and operating temperature at 25°C, the temperature of CPU is around +80°C. If the operating temperature is higher, the temperature of CPU will exceed +85°C.

Although there are no risk to damage the CPU when your system work at higher temperature, CPU will lower its operating frequency, the system will operate at protected mode, the processing performance is lower.

Normally if the system continues to operate at high temperature, the product life and system stability will be reduced.

So the thermal design should be considered.
