TS-8551-socket

The TS-SOCKET SoM devices all use 2 high density 100 pin connectors for power and all I/O. These follow a common pinout for various external interfaces so new modules can be switched in to an application in order to lower power consumption or use a more powerful processor. The male connector is on the baseboard, and the female connector is on the SoM. The datasheet for the baseboard's male connector can be found here. Connectors can be ordered from the SoM's product page as CN-TSSOCKET-M-10 for a 10 pack, or CN-TSSOCKET-M-100 for 100 pieces, or from the vendor of your choice; the part is an FCI 61083-102402LF.

In our schematics and our table layout below, we refer to pin 1 from the male connector on the baseboard.

On the TS-8551, the entirety of both high-density connectors are broken out in to 0.1" spaced 2x25 pin headers. There are 4 of these in total, one each for CN1 odd numbered pins, CN1 even numbered pins, CN2 even numbered pins, and CN2 odd numbered pins. They are labeled on the silkscreen every 10 pins, with the first 2 and last 2 pins also being labeled.

Note that the below pinout is from the perspective of the TS-8551. However, the links for each pin will link to the relevant section in this manual. When designing a custom baseboard, it is advised to consider both the TS-8551's TS-SOCKET pinout and functions as well as the target SoM's pinout. For details on a specific SoM's interface, see that device's manual.
