Hello NCD community!
I want to power the 2-channel 4-20mA current loop I2C board with my Particle electron.
The Electron uses 3.3V but I need 5V to power the board (and maybe other boards in the future) through the electron.
I figured a power booster can be used together with a load switch to make this work.
If I use a load switch to enable/disable 3v3 pin connected to a boost converter (3.3V to 5V), i can cut the power when I don’t use the 4-20mA sensor board.
The boost converter then converts the 3v3 to 5v and the 4-20mA sensor board is powered. This should be possible, right?
I found these boost converters:

and these load switches:

Are these usable for this situation?
Thanks in advance,
