The RasPiO Pro Hat is gear upwards to operate similar a shot out of the box equally it comes fully assembled (no soldering or software installation required). All yous convey to exercise is construct a circuit on the breadboard together with command it amongst GPIO Zero (or RPi.GPIO etc).
With the RasPiO Pro Hat yous also conk access to unprotected ports via unpopulated header if yous desire to bypass the 330 Ohm resistor on whatever of the ports. As far equally the port protection, it uses a 330R resistor inward serial amongst each port to limit electrical flow to x mA per port. Influenza A virus subtype H5N1 3V3 Zener diode 'clips' whatever over-voltage together with diverts the excess to GND. It also protects against modest negative voltage ( -1V). The RasPiO Pro Hat is suitable for all 40-pin Raspberry Pi models (Raspberry Pi B+, Raspberry Pi A+, Raspberry Pi2B, together with Raspberry Pi Zero).
