QIANDUOO 5pcs 5V-3V Level Transformation Module Shifter Bi-Directional Four Rows Of Needle

hey guys what's happening today we are going to take a look at this word you see right here and it is a bi-directional level shifter okay sibling get her to focus there we go so this is the high side that takes your 5 volt signals and this is below side for the low voltage signals and you see we have resistors and some MOSFETs these are KSA 1290 and the way this works is when we are going to put this down here when we are going from 5 volt to 3.3 volts the two resistors come into play and it behaves as a voltage divider and it's locks in voltage down to 66 percent so 66 percent of 5 volt is 3.3 volts however you cannot voltage divided up so that is where this TNT at the taxol transistor comes in and it knocks the voltage up so what I've got mocked up here is like a little sample circuit and let me finish hooking it up here so we can see I'll plug my ground in there and I'm going to put
