The mass storage capabilities of the SBC-A80-eNUC are
completed by an M.2 SSD Slot, which allow plugging M.2
Socket 2 Key B Solid State Drives.
The connector used for the M.2 SSD slot is CN17, which is
a standard 75 pin M.2 Key B connector, type LOTES p/n
APCI0087-P001A, H=8.5mm, with the pinout shown in the
table on the left.
On the SBC-A80-eNUC board there is also a Threaded
Spacer which allows the placement of M.2 Socket 2 Key B
SSD modules in 2260 size.
It is possible to place also modules in 2242size, by using a M/F Spacer which allow fixing the
M.2 SSD on the spacer already available on the PCB, deemed for the fixing of the M.2
connectivity slot (see next paragraph)
Here following the signals related to this SATA interface:
SATA0_TX+/SATA0_TX-: Serial ATA Channel #0 Transmit differential pair
SATA0_RX+/SATA0_RX-: Serial ATA Channel #0 Receive differential pair
10nF AC series decoupling capacitors are placed on each line of SATA differential pairs.
