GPIO Resistor Configuration

The GPIO Resistor configuration is populated for default device configuration but designed for flexibility. All GPIO signals have a 0 Ohm 0402 resistors that connect the GPIO signal to a Jumper-configurable resistor network. GPIO3 and GPIO4 additionally can be pulled up to VIO or SYS through J34. GPIO4 additionally can be used to exhibit PWM functionality through D1 diode, where pull up voltage can be attached at J35 and requires a resistor placed at R21.

VIO Selection

VIO serves as the digital pull-up rail for the EVM. Various rails can be selected as the rail intended for as the supply for this rail. J14 allows simple changing between Buck, Buck-Boost, or the SYS rail. An external LDO can be used by populating R7, though J14 should be disconnected at this point. This external LDO input rail can be selected via the J3 header.
