Description

Product Details

Frequency 500 MHz
Operating Supply Voltage +3.3 V DC
Interface Type M.2 key E (2 clock lines)
Minimum Operating Temperature -40C
Maximum Operating Temperature +85C

WARNING:
This M.2 Key E product is for experts only, it will NOT be detected on most M.2 key E systems. On those that can detect it, only ONE of the two TPUs will be available, since most M.2 Key E systems only support one PCIe bus.

To support 2 PCIe buses we need TWO clock lines, refer to pin 71 and 73 on page 6 of the datasheet:
https://coral.ai/docs/m2-dual-edgetpu/datasheet/
Discussion on this is available here:
https://github.com/google-coral/edgetpu/issues/256

A crazy proposal is to use PCIe packet switching to access both TPUs over one PCIe bus, that is left as an exercise to the reader.
