Hello,
I’m designing my own minimal PCB. To do this, I’m taking inspiration from the diagram of the AIO v4.5 boards. I’m currently working on the ADS1115 part and I believe there’s a problem with the ADDR pin. Regarding the ADS1115 datasheet, ADDR pin can be connected to GND, VDD, SCL or SDA. On the AIO v4.5 bord, this pin is connected to nothing. Floating input pin is generaly a bad idea in electronic design.
So what is the correct connexion for this pin ? I presume it’s to GND (0x48) but i prefer cofirmation.
thank you
You need 5 pins, Vdd, Gnd, Scl, Sda, and one of the analog inputs.
