Additional GPIO expansion connector
Additional unused I/Os and a few shared I/Os of the PSoC
™
4100S Max MCU are brought out to this connector.
This connector is not populated by default. Five shared I/Os are not connected to these connector pads, by
default. Zero-ohm resistor configuration needs to be changed to connect those I/Os to this expansion
connector.
