If you fancy building your own USB flash drives then we can supply you with the core component around which you just add your own “shell”. 

The Self Build USB flash drive we supply is a PCB with an on-board USB flash memory, a controller chip and a USB connector.

They come in all the usual sizes from 128MB all the way up to 64GB.

Your challenge (or your pupils challenge if you buy these for a school project) is to design, fabricate and then fit the shell around the USB. Easy!
