M.2 Slot
M.2 is formerly known as Next Generation Form Factor (NGFF) and is located at JMD1 on
the motherboard. The M.2 slot is designed for internal mounting devices. The A2SAP-H/-E/-L
motherboard deploys a B-KEY for SATA/PCI-E SSD devices or USB/PCI-E WWAN or GNSS
card. The A2SAP-H/-E/-L deploys a 2280 screw hole location for a 2280 M.2 module. 2242
and 3042 M.2 modules are supported by an extender bracket to t on the 2280 screw hole
location.
