About this item

The PIMORONI MMC HAT is a versatile add-on board designed to expand the storage capabilities of your Raspberry Pi by adding a microSD card slot for extra memory. It’s compatible with a wide range of Raspberry Pi models, including the A+, B+, Zero (with headers), Zero W (with headers), 2B, 3B, 3B+, and 4B. This flexibility makes it an excellent choice for users looking to enhance storage without compromising the compactness of their Pi projects.When used with Raspberry Pi models like the Zero W, 3B, or 3B+, the MMC HAT disables the onboard WiFi. This is because the onboard WiFi uses the SDIO interface, which the MMC HAT also utilizes for communication. Despite this trade-off, the HAT offers reliable high-speed data transfer and ample storage space through its dedicated microSD slot, ideal for applications that require robust data logging, media storage, or offline project setups.The MMC HAT connects easily to the Pi’s GPIO header and fits neatly on top, maintaining a clean and compact setup. It’s especially useful in projects where USB storage or network access isn’t ideal or possible.
