5.3 SMARC sAT30 I/O
The SMARC sAT30 module provides multiple I/O lines for various functions. 12 I/Os lines are used as interrupt
capable GPIOs, which follow SMARC hardware specification. GPIO5 PWM output and GPIO6 Tachometer input support is
also provided as per the SMARC hardware specification.
Caution! These details are provided for reference. Generally, access to the I/O is abstracted in the Kontron BSP
packages.
GPIO functionality as well as I/O mapping to the SMARC sAT30 connector is shown below:
