There are four High density connectors in the HSEC Adapter Board which are referenced as J1, J2, J3 and J4.
J1 connector supports the ADC (Analog to Digital Converter), FSI (Fast serial interface), eQEP (Enhanced quadrature encoder plus), SDFM (Sigma Delta Filter Module), I2C, JTAG, CAN, PWM, SPI, UART, and GPIO signals. Also, the HSEC Adapter board get the 3V3 supply from the J1 connector.
J2 connector supports the ADC (Analog to digital converter), FSI (Fast serial interface), SDFM (Sigma Delta Filter), PWM, SPI, CAN, UART, and USB signals.
J3 connector supports the SPI, CAN, I2C, GPIO, UART and EtherCAT PHY. Also, HSEC module gets the power from the J3 connector.
