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 APCI0095-P001A, H=8.5mm, with the pinout
shown in the table on the left.
On the SBC-D23 board there is also a Threaded Spacer which allows the placement of M.2
Socket 1 Key E connectivity modules in 2230/3030 size.
This slot only supports M.2 Socket 1 Key E modules using SDIO and UART interfaces; it
-e and/or USB interfaces.
Here following the description of the signals available on this slot
SDIO_CLK: PX30 SDIO interface Clock Line, +1P8V_VDD electrical level Output
SDIO_CMD: PX30 SDIO Command/Response, +1P8V_VDD electrical level bidirectional line.
