Circuits@Home Mini USB Host Shield: Pro Mini vs Pro Micro

The Circuits@Home Mini USB Host Shield,

https://www.circuitsathome.com/usb-host ... are-manual

is compatible with a Arduino Pro Mini 328 - 3.3V/8MHz. The Arduino Pro Mini 328 would appear to be "somewhat" pin-compatible with a SparkFun Pro Micro - 3.3V/8MHz. What are my chances the Circuits@Home Mini USB Host Shield will work with the SparkFun Pro Micro? Has anyone successfully integrate the Circuits@Home Mini USB Host Shield with the SparkFun Pro Micro?

Thank you,

Joe

Even if you haven't integrated a Circuits@Home Mini USB Host Shield with a SparkFun Pro Micro - 3.3V/8MHz, can someone please comment on whether I can expect a Pro Micro to be pin-compatible with a Arduino Pro Mini 328 - 3.3V/8MHz? For example, can I count on the SPI signals (SS, MOSI, MISO, and SCK) being pin-compatible between the Mini and Micro?
