TS-4900 TS-Socket interface
The TS-SOCKET macrocontrollers all use two 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 dropped in to lower power consumption or use a more powerful processor. The male connector is on the baseboard, and the female connector is on the macrocontroller. You can find the datasheet for the baseboard's male connector here. This can be ordered from the TS-Socket macrocontroller product page as CN-TSSOCKET-M-10 for a 10 pack, or CN-TSSOCKET-M-100 for 100 pieces.
In our schematics and our table layout below, we refer to pin 1 from the male connector on the baseboard. For designing a custom carrier board for the TS-4900 we recommend using the TS-8550 as a base: https://www.embeddedarm.com/documentation/ts-8550-schematic.pdf
