I am looking at some tutorials and i see this shit over and over again
>alright the module is NOT 5V tolerant you have to be careful, use the 3.3V pin on the UNO to connect the power to the module
and then those retards connect the digital connection wires directly like in pic related
nigger, you do realize those logical pins on UNO are still 5V right? and those digital pins on the module are definitely not 5V tolerant (and it does not have any level shifter either)
is see this mistake so fucking often it's ridiculous
