I have it set up so that the arduino on the low voltage circuit plugs into the “in” side of the isolator, and it provides isolated 5v to the arduino on the high voltage circuit as it should.- Google Patents US6407402B1 - I2C opto-isolator circuit The purpose of isolating these two arduinos is that one of the arduinos is “floating” on the HV circuit and is using an ADC to read high voltages on the high voltage circuit cannot be grounded with our low voltage circuit with the other arduino on it. I cannot send i2c from the high voltage to the low voltage arduino which is the whole purpose of isolating the signal. I can only send data from the arduino on low voltage and can only read it from the arduino on the high voltage. The issue is that I can’t seem to get bidirectional i2c data. I used your product because it looks like it should isolate i2c bidirectionally as well as providing regulated 5v power to another arduino. Hey, I recently bought the “ISO1541 I2C Data and 1KV Power Isolator Bus Handler I2C Mini Module” in order to create optically isolated i2c communication between 2 arduinos.
