Hi guys, I "designed" this based on the the size of 3 18650 holders (maybe overkill I know, in //). The point is to use the 4 analog input of the ADS1115 with capacity moisture sensors like this :

The A0 of the Esp will be to monitor the batteries. I may use I²C with an Oled & motion sensor to display values. May also add solar panel...
Here's where I am so far, any advice is welcome.

Maybe also add a header for an extra 3v3 input?
There are Wemos modules out there with limited 3v3 voltage regulators.
For example one of those: https://nl.aliexpress.com/item/32829322098.html

Indeed. Thanks I'll do that and redesign it.
