Using Node Red to Control the PCA9536

GPIO in minutes If you haven’t already, make sure to go through the setup tutorial. Once you’ve finished that we’re ready to go! The PCA9536 is an 8-pin CMOS device that provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion through the I2C bus. We manufacture multiple mini-modules that utilize this chip, you can check them out here. If you haven’t already, get your devices plugged in, on a Raspberry Pi, that means installing the adapter, hooking up the I2C cable to the In port on the Relay Board, and powering the board. On any platform without native I2C,
