Hello all
As you can see this is my first post on this forum. I have been following the forum as a guest viewer only for a while, but now it's time for my first post .
I have made a schematic of a wifi sensor node with an internal temp/humidity sensor and inputs for 4 external analog moisture sensors.
I am going to start by having a small batch of 10 units produced and assembled, but before i order it, I would really appreciate some secondary opinion of the design.
I am mostly not sure about if i connected the USB plug and the 5V -> 3.3V v-reg (AP1117) and the Torex XC9128 3.3V boost supply from the batteries correctly to each other.
Will I waste my money sending this to the PCB manufacturer?
Please take a look at schematics and tell me what you think
The moisture sensor is VH400 ( http://www.vegetronix.com/Products/VH400/ )
The moisture sensors outputs 0-3.3V and runs of 3.3V-20V
