So it does exist as spotted by sharp eyes and was not a mirage after all! But to get Megrez up to feature parity to Oasis with the hardware that got people’s attention? It is unlikely that modifying the Megrez will be cheaper. Having to make minimal and least costly changes was part of the consideration with the suggestion for going to the CM form factor. To enable the compute module for Oasis, only 2 inexpensive connectors are needed and to redo the traces around the current SoC area.
As mentioned the appeal for Oasis was not only with the 16-core processor, but also the board features like 4x SATA, 3x M.2 (which includes NVMe PCIe), eDP, MIPI CSI, LPCAMM2 that are currently not there on Megrez. Those are a lot more components to add, and rearrange existing electronics around for the necessary controllers and physical interfaces. On top of that it requires retracing throughout the entire board.
Also by adding these features to the Megrez, wouldn’t that make it - the Oasis board…
