The ADS1115 has 4 analogue ports and you can see details at Hooked up ESP to Nano = fail, but can i hook Nano to ESP?
The link includes a video of the analogue port extender running with Blynk on a “plug and play” ESP board.
Available on AliExpress for under 2 bucks.
I believe there are boards available with more than 4 ports and to be honest I would prefer to run 2 plug and play boards than one plug and prey board.
