m.2 two instances of PCIe x1?

machinevision · February 2021

Does the up squared board m.2 slot support:

Although the M.2 Specification (section 5.1.2) declares E-key sockets provide two instances of PCIe x1, most manufacturers provide only one. To use both Edge TPUs, be sure your socket connects both instances to the host.

As per the specifications of the coral AI module here, https://coral.ai/docs/m2-dual-edgetpu/datasheet/, there are pins(PET/PERx1) on the module, which are not connected to anything on our UP Squared board, hence it would not be able to support this module.

Thanks,

So far all UP family supports only 1x PCIe on M.2 2230. We are going to look into it if we can support 2x PCIe in the future design.
