This is a work-in-progress list of Sansa accessories tested with Rockbox. Some accessories for the Sansa which connect via the dock adapter do not work with Rockbox. This is because they use a as of yet unresearched (and hence not implemented in Rockbox) way of communicating with the Sansa. What follows is a list of accessories, and whether or not they work in Rockbox in any fashion at all.
When adding information to the chart, please be a good boy (or girl) and fill in the Model Number if you can. Many manufacturers have released different physical models under the same (or confusingly similar) name. Please also be good enough to list the model of Sansa you tested on (although it should hopefully not matter).
