2.4.2 HSEC Pinout

The 180-pin High Speed Edge Connector (HSEC) connects to an HSEC docking station. This interface provides power to the SOM to HSEC adapter board and controlSOM through the SOM HD connectors. In addition, the HSEC pins bring out analog and digital IO from the controlSOM and allow access to prototyping using these interfaces, such as SPI, I2C, UART, FSI, EQEP, PRU-ICSS, EPWM, and ADC.

Table 2-2 details the HSEC pinout. The pinout can also be found in the HSEC180ADAPEVM-AM2 design files package in the PROC195E1(001)_SOM_to_AM26x-HSEC.pdf file.
