Is spi open collector
WitrynaWhen combined with other components, the Open Collector Output can be used to drive LEDs, indicators, small pumps or relays (to operate larger pumps). Alternatively, the switch can drive an input to a controller such as a PLC or a computer board such as a Raspberry PI or an Arduino (please see instructions of the PLC/computer on how to … WitrynaSPI: open collector output and totem-pole output. These types of optocouplers only integrate up to two channels, which means two to four optocouplers have to be used …
