Tatooine R5 unit
From Wookieepedia, the Star Wars wiki.
This R5-series astromech droid was owned by a moisture farmer living on Tatooine in 14 ABY. The farmer ordered the droid to record a conversation about the Disciples of Ragnos that he had overheard in a local bar. When he became fearful of reprisals from the cult, he sold the droid to a band of Jawas. Kyle Katarn and Jaden Korr were sent to the desert world in order to purchase the droid from the Jawas.
[edit] Behind the scenes
The R5 unit is canonical, appearing in Star Wars: Jedi Knight: Jedi Academy, but has not been named.
