Description
Facing shortages of standard Raspberry Pi 4B boards or requiring industrial-grade onboard eMMC storage for mission-critical deployments? The Waveshare CM4 to Pi 4B Adapter Board provides a seamless interface expansion solution, converting any Raspberry Pi Compute Module 4 (Lite or eMMC variants) into the universally recognized Raspberry Pi 4B mechanical layout.
Engineered with an onboard high-density CM4 socket, this board grants instant access to the Quad-Core Cortex-A72 computing power of the CM4. It bridges the module’s high-speed lines to standard peripheral connectors, featuring an onboard USB 3.0 hub supplying four USB 3.0 ports. Additionally, it provides a 10/100/1000M adaptive Gigabit Ethernet port, Power over Ethernet (PoE) expansion header, and full 40-pin GPIO header compatibility for standard Pi HATs.
