Now its time for the resistors. **WARNING** R1 has polarity! Pin one must be at the side where R1 is noted. The other resistors dont have polarity but have different values, R2/R3 are 4K7 and R4 is 10K.
Now its time for the resistors. **WARNING** R1 has polarity! Pin one (marked with a dot) should be at the side with the diagonal corner, next to the jumpers (opposite of the R1 marking).

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 its an easy job, the choice 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.
