The nanopi4 boards differ primarily in their power trees, with the main 5V and 3.3V rails having very different topologies on the smaller USB-C powered boards vs. the 12V-powered T4, as well as minor variation in other regulators related to various external connectors. Additionally, the recovery key is only present on the T4 - ADC_IN1 is simply pulled high and not exposed on the other boards - and the lowest common denominator for MMC speed is actually HS200 according to the vendor DTs.
