The Ware for June 2016 is an ATS810C by ATS Automation. There’s no information on their website about this particular board, but there’s lots of good ideas in the comments as to what this could be from. However, none of them have me 100% convinced. So I’ll just go with the first answer that generally identified the ware as a stepper motor controller with RS-232 interface by notafile. Congrats, email me for your prize!
