Sixteen LV Digital Inputs 8-Layer Stackable HAT for Raspberry Pi (v3.1) [Discontinued] Brand_Hitaltech It is completely stand-alone andRaspberry Pi can read 26 Input signals through the GPIO header, but sometimes you might need to read more. Since all GPIO pins are wired directly to the local processor, some hardware is required to connect them to the real world. This card has sixteen optically isolated Digital Inputs. Input ranges can be jumper selected for each channel, from 3 volts to 48 volts. Digital Inputs can read both DC and AC signals. The card communicates with Raspberry Pi
