I have an ACS712 (5v sensor), an ADS1115 (5 or 3.3v) and an ESP8266 board (3.3v).
I know I can't directly use the ACS with the ESP without a voltage divider on the analog pin. So I figured I could run the ADS and the ACS off 5 volts as the ADS communicates over I2C. Does this cause any issues with the SDA/SCL lines on the ESP?
What is the correct way in going about this?
