What size microSD card do I need for the Pi Cap?
We recommend you use an 8 GB or larger microSD card which has been loaded with Raspbian or NOOBS. You can purchase either of these directly from the PiHut.
We also recommend always using a genuine SD card. Cheaper cards are often slow or erratic in performance, smaller than advertised and tend not to last long. A little extra money spent in advance is well worth it.
