The mass storage capabilities of the CCOME-C30 carrier
board 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 CN13, 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 CCOME-C30 carrier 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 WLAN
slot (see paragraph 3.3.6)
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
Please be aware that M.2 SSD slot will work only in case the COM Express module carries
out SATA Channel #0 on COM Express connector (pins A16, A17, A19 and A20). In case the
COM Express module used doesn't have these signals connected, then this slot will not be
usable.
