mofosyne shared this Bus Pirate reference sheet [PDF!] he made in the forum:
Being new to bus pirate, I created my own printable stickers to cut and stick labels to the case and probes.
I also took the time to compile an A4 Bus Pirate v3.b reference sheet from various sources, that would be useful to somebody with a smartphone to scan the various QR codes on it. This was created in the mind of somebody who wont be using the Bus Pirate too often, and may occasionally need a refresher to jig their memory. Its free for anybody to use as it is just a handy compilation for me, all sources are linked to if you need to know more about it.
