T-SIM7600E/G-H without battery?
-
Hi, I'm looking for something like the T-SIM7600E/G-H but without a battery holder.
Basically need something that is as compact as possible and comes with all basic MCU, LTE, and SIM card necessities but assumes an external power source. Is this possible or am I stuck with the battery or can I use some alternative to the T-SIM7600E/G-H?
I'm particularly looking at this listing variant:

I'm using the Lilygo SIM7000g.
In my case I can power the board with the 3.3 pin but only if the voltage is higher than 3.7v. I also used 5v in the VIN pin and let it run for a while. But when the voltage did go up to 6v I broke something.
So you can use the board without battery, I even broke the 18500 of the board.
Does someone know what fuse I need to replace from the VIN pin? Schematics I count find it.

Typically electronic boards do not have a fuse.
A fuse is used only to protect the wiring from catching fire.
Solid state components fail in microseconds and fuse cannot react fast enough.
I checked the schematic and did not see one!

@covalspace Do you already have a LilyGo SIM7000g?
Could you just remove the battery holder?
