OLED 128x64 font license

I like the fixed width font that is provided in the OLED example code. I’d like to distribute it with some other, MIT licensed code. There are no license markings on the source for the font itself. Under what terms may I redistribute it?

Thanks,
Andrew

Thank you, that will do.

I have a bunch of other CC BY-SA 3.0 code, so I am familiar with the terms, and they are satisfactory.

I will add the appropriate headers and a copyright notice for Seeed Studio.
