I’m trying to power a 3g USB dongle from a simple booster powered by an 18650 lipo. I’m using a generic all in one converter board from my local hobby electronics store and it works fine.
The problem is I want to only power this circuit for short periods. When I try to control with a N-MOSFET switching ground via esp32, the dongle keeps resetting before it can establish a connection, presumably because of voltage drop?
I’m away from my workshop for a few days and can’t remember the specific MOSFET. I’m probably not using the best MOSFET for the job, but rather than asking another “which MOSFET should I use” thread, I thought I’d ask if anyone knows of a ready made 2-4v to usb booster which is controllable/switchable using 3v logic?
It would make life so much easier
