You can choose to use a precision IC-mount or solder the MCP23017 directly to the PCB. We prefer an IC-mount so if you need to change the IC in the future it’s an easy job, choose is yours ;) If you choose to use an IC-mount note that it has polarity! The MCP23017 has polarity as well, the dot on the main PCB notes for pin 1, the must be corresponding with the dot on the MCP23017.
