Description:
The CM4-NANO-B is an ultra-compact expansion board designed specifically for the Raspberry Pi Compute Module 4 (CM4). Despite its small footprint, this Type B baseboard efficiently breaks out all the essential interfaces of the CM4, enabling easy integration into embedded systems and space-constrained applications. Its form factor matches the size of the CM4 itself, making it ideal for minimalistic and high-density setups without compromising functionality.
