If this chip is connected like this, will it work when connected to a PC? [Copy link]

This chip seems to be connected very casually... Can it be used directly after connecting to a computer? ?

IC 21006541 Magtek A head decoding chip... I'm wondering how this thing can be connected to a computer through a microcontroller. Or can it be directly connected to a computer? And can this chip start working when it is powered independently?

Just connect it and you will know. I think it can work.

Can it be used directly? So awesome? ? ? ? ? ? ? Don’t you need to convert the signal? Just connect it to a USB port? ? It feels a bit incredible

Didn't you see how it was connected to the computer? It was taken out of the 1 yuan POS machine? There is no point in studying this kind of circuit, because the EMV migration was probably in 2005, and the backward China finally implemented it 10 years later.

The OP should find the device manual of the chip on the board and read it carefully. Once you understand it, you will naturally know how to do it.
