The 180-pin HSEC edge connector provides the power to the SOM, which is going to connect with the HSEC through a high-density connector. For powering and validating various interfaces the 180-pin edge connector is mated with the docking station (TMDSHSECDOCK). The interfaces like SPI, I2C, UART, FSI, JTAG, ADC can be validated through the docking station pins.
Refer to the image below for the connector pins details with the interfaced signal names.
