I want to make a new PCB that will have low power consumption (puting off circuit some components (CP2104 ,RT9013) with swithces and supplying voltage (3.3V) with a dc-dc converter).
And if I want to put them again in the circuit, I put the switches to ON.
The current PCB is too tiny to make these mods on it.
I want to remove the components from it and 'move' them to this new PCB that I'm going to make.
(I repeat, the reason for the new PCB is that I want to make it work in low consumption)
So I want to add to the new PCB:
1. swicthes to the VIO and VDD pins of CP2104 that will put them ON or OFF the circuit
2. switch to the VIN pin of RT9013
Something else that I should add the ability to put it off circuit?
Is my idea good?
(how can I desolder the antenna connector on the PCB? part of it is plastic. I think hot air could destroy it. With soldering iron maybe?)
(I 'm using WEMOS because it has extended range of WiFi)
It 's schematic is this: https://wiki.wemos.cc/_media/products:d ... v1.0.0.pdf
