M.2 Sockets
The M.2 socket is the Next Generation Form Factor (NGFF) which is designed to support mul-
tiple modules and make the M.2 more suitable in application for solid-state storage. The board
preserves space and two standoffs for the M.2 M Key socket (22mm x 80mm).
Mini PCIe
The Mini PCIe socket allows for a full-size Mini PCIe module, and supports PCIe and USB sig-
nals.
Nano SIM (optional)
The Nano SIM socket allows for inserting a Nano SIM card for the system to access the sub-
scribed telecom service.
