Steve Francis just posed for another mug shot, 'cause he finally turned himself in on a warrant stemming from a burglary charge earlier this year.

As we previously reported, the ex-NBA star was wanted by cops in Manatee, Florida after he allegedly ransacked a stranger's car back in June and stole over $7k in stuff.

Francis was arrested for DWI in Houston a few weeks ago -- and when Florida police caught wind of that, they issued a warrant for his arrest for the burglary incident.

According to jail records, Francis turned himself in early Monday on a burglary of an unoccupied conveyance charge -- a 3rd degree felony that carries up to 5 years in prison.
