Is the MarCM Worth Considering as a Compute Module 4 Replacement?

TLDRThe MarCM is a tiny computer that aims to be a drop-in replacement for the Raspberry Pi Compute Module 4. However, it falls short in terms of performance and compatibility. While it offers features like 4K support, Bluetooth, Wi-Fi, and gigabit Ethernet, it lacks hardware PTP timestamping and compatibility with certain software. Additionally, its processor is slower compared to other ARM cores. Despite its limitations, the MarCM can still be a viable option if you're interested in exploring a new architecture or need a computer for a compute module board. It's not recommended for typical users and might not be suitable as a Compute Module 4 killer.
