The MMC HAT (Hardware Attached on Top) adds a second microSD socket to your Raspberry Pi using the second (or third) SDIO interface.
It can be used with Raspberry Pi A+, B+, Zero (with headers), Zero W* (with headers), 2B, 3B*, 3B+* and 4B (* When used on a Raspberry Pi Zero W, 3B or 3B+ the onboard WiFi is disabled as it is on the SDIO interface used by the MMC HAT).
The Raspberry Pi 4 has three SD controllers so you can use onboard SD, WiFi, and the MMC HAT (SD) at the same time on the Pi4!
