EDD comes with a Download Details widget available. This widget allows you to display the details for a product in a widget area. You may set the title, the Download, and any of 4 things to render. The admin UI is visible below on the left. An example front-end view is available on the right.
If you choose “Use Current” the widget disappears on pages that do not have a Single Download on them.
Your other options are any Download in your store.
