the Coral M.2 Accelerator with Dual Edge TPU
M.2 Accelerator with Dual Edge TPU | Coral
Connector parameter ：M.2 E-key (with two PCIe Gen2 x1 lanes)*
the X1 M.2 socket 2230
ps.the pin 22,32,34,36 with"CNVI" is the PCIE signal，should work with the Coral TPU module
Recommend to use the M.2 socket 2280(with PCIE signal)
and buy a Adapter boad M-KEY → E-key like this
maybe it will work
