This board is available with RJ45 sockets (P140-R) or Xcode sockets (P140-M)

At full power, the Power Inductor should be cooled.

P140 is compatible to the following carrier boards:

JNX30
JNX30M
JNX42
X221D
X230D

If the carrier board has no PCIex1 interface, P140 can be connected to other carrier boards with M52 M.2 Key M to PCIe X1.
For example JNX30D,X221, 230.
