Actually, I bought these Core Boards for their simplicity but also for their High Speed and Large Ram Capabilities,
- like using for Camera Video Processing. Additional Ext Chip seems like extra labor - and wasted resources.
I want to use them for the many Robots that I build.
I have about 60 Robots currently being Developed now here in my Lab at home at the moment.
(not including the many Robots that I have already built in past years)
