M.2 2230 Socket 1 Key E Connectivity Slot
It is possible to increase the connectivity of the SBC-C43
board by using M.2 Socket 1 Key E connectivity slot.
The connector used for the M.2 Connectivity slot is CN36,
which is a standard 75 pin M.2 Key E connector, type
LOTES p/n APCI0076-P001A, H=4.2mm, with the pinout
shown in the table on the left.
On the SBC-C43 board there is also a Threaded Spacer
which allows the placement of M.2 Socket 1 Key E connectivity modules in 2230 size.
