This peripheral module is designed for use with FPGA, CPLD or Microcontroller development boards.
PMOPIN - 4 optocoupled inputs peripheral module, active-low, with pull-up resistors.
Can be used to connect high voltage signals or to avoid common ground.
Maximum input voltage is 9 volts. Voltage can be increased by adding additional serial resistors.
Module has "common GND mode" and "common VCC mode", for connecting remote switch.
Module has "full isolation mode", for connecting external signal.
1x PMOPIN module
