I first made a version with two mosfets, then decided to simplify and kept one. Now it looks like this.
Thank you for your response. I will order another rp2040 just in case.
I know the mosfet can be replaced. I just want to make sure that the problem is definitely in the transistor and not something else. Soldering such small things is very tedious for me.
Guys, does the "long long short" error only appear if there is a mosfet problem or could there be another reason? I tried the circuit with two and one mosfet, but I get this error every time.
(switch lite)
Hey, everybody. I am currently trying to install rp2040-zero on ns lite. I soldered the mosfets to the capacitors and found that DRAIN and SOURCE are shorted. Also both pins of the capacitors (that I soldered to) are on ground.
I am not very knowledgeable in radio electronics. Perhaps there is...
I think it’s not very difficult to find out what kind of chips these are. It is enough to dissolve the body in acid and look at the silicon under a microscope.
If this is true, it sucks. I don't think the price will be much lower than existing solutions. But perhaps it is possible to read the program from the chip?
