Raspberry Pi CM4 IO Board CM4 to 4B interface expansion board CM4 to PI4B Adapter, Compatible with 4B Size and functions same as much as possible.

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.

Raspberry Pi Compute Module 4 incorporates a quad-core ARM Cortex-A72 processor, dual video output, and a wide selection of other interfaces. Available in 32 variants, with a range of RAM and eMMC Flash options, and with or without wireless connectivity.

USB do not work ? --> USB 2.0 is close by default, if used dtoverlay=dwc2,dr_mode=host should be added in config.txt

Note 1: This product is not Raspberry Pi 4B, It is a Raspberry Pi 4B Compatible board which Converted from CM4 Compute Module board CM4101000

Note 2: This product include "CM4 core board " + " CM4 to 4B interface IO Board" . Not include a Raspberry Pi 4B

Features introduction

If you want to use Raspberry Pi 4B but worried that it is often damaged, We recommend to choose this product.
After it damaged, only need replace a cheap CM4 core board
We recommend this when you want to use Raspberry Pi 4B and Raspberry Pi CM4 at the same time.

Compute Module 4 Overview

CM4101000 with WIFI/RAM-1G/eMMC-0GB(Lite)
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.
Raspberry Pi Compute Module 4 incorporates a quad-core ARM Cortex-A72 processor, dual video output, and a wide selection of other interfaces. Available in 32 variants, with a range of RAM and eMMC Flash options, and with or without wireless connectivity.

Upgraded processor BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC, more powerful performance
More options for RAM (1GB/2GB/4GB/8GB), competent for large-scale data compilation
Faster eMMC Flash storage, up to 100 MBytes/s data rate, which is four times faster than the CM3+
Option for fully certified radio module, the same one used on Pi4B, supports either PCB trace antenna or external antenna, more suitable for industrial applications
Adopts B to B connectors, more stable than the Goldfinger edge connector of previous generations
Onboard new Gigabit Ethernet PHY supporting IEEE1588, suitable for network applications
Onboard new PCIe Gen 2 x1 interface, allows connecting more useful modules
