Hi Erik, The JTAG pads looks a little different from usual JTAG pads for previous BeagleBone series. Is there cables or connectors that I can connect those pads?

I also noticed that the OSD335x-SM has got a EEPROM, which previous OSD335x module doesn't have. So basically OSD335x-SM is just a smaller and slightly better module than the previous one?

Yes. Unfortunately, with the form factor of the PocketBeagle, it was not able to use a standard JTAG connector footprint. I do not know of any standard cables or connectors to connect to those pads. I would also ask on the BeagleBoard forums.

Yes. The OSD335x-SM is a smaller and more optimized module than the original OSD335x. Based on customer feedback from the OSD335x, we optimized the pin out to ease routing and reduced the size to enable more space constrained applications (The OSD335x-SM is 60% smaller than a discrete implementation: https://octavosystems.com/2017/08/30/smaller-cheaper-pcbs/)
