I purchased two more quad relays (the first one has another issue), I am now using a 9V power supply. I am connected to an OpenMV using the qwiic connecter to male jumper. The LED for the barrel jack illuminates, but when I scan for the I2C address, it does not return the slave (quad relay). Is 3.3 V enough power to power the logic side? I did get two single qwiic relays working with the openmv. thank you for your guidance.
Hmm…3.3v should be enough for the logic control - could you share a photo of your set-up and a wiring diagram?
