Compute Module 4
Raspberry Pi 4 on a 55 × 40 mm module with no connectors of its own, for building into products on a carrier board, with 1 GB to 8 GB of memory and optional eMMC storage and wireless.
- Processor
- Broadcom BCM2711 (Arm Cortex-A72)
- Clock
- 1.5 GHz
- Memory
- 1 GB – 8 GB
- Wi-Fi
- Yes
What reviewers say
Reviewers agree it puts Raspberry Pi 4 performance, native PCIe and optional wireless into a compact module well suited to embedded projects and custom carrier boards. Tom's Hardware found it expensive and suited only to those with the skills to design around it; Jeff Geerling found the official IO board large and the module fiddly to detach.

Pros and cons
Pros
- PCIe Gen 2 x1 interface, unlike Raspberry Pi 4
- Two 4-lane MIPI camera and display interfaces as well as two 2-lane ones
- Versions rated for −20°C to +85°C, with extended-temperature ones down to −40°C
Cons
- Needs a carrier board (such as the CM4 IO Board) for any ports
- Wi-Fi, Bluetooth and eMMC depend on the version bought
- 1.5GHz, slower than Raspberry Pi 4's current 1.8GHz
