@davee @allocsb I think it's time to remind everyone of the original issue. It seems that the pn532 only enumerates under i2c for me when it's con...

@huckohio @josiah430 YES, I forgot to mention that.

@davee @allocsb I looked at the datasheet I think you provided. I read most of it including the power section. 5V goes into an LDO and 3.3V comes out ...

@josiah430 Some folks like the old 1.8, some the new 2.3. I like 2.3. At first it seemed foreign, but now I enjoy all it's extra features and don't mi...

@josiah430 Ok, it is something that happens quite a bit for some folks, just be patient and try again.

@josiah430 Ok. First, close the IDE and restart. Then select your board (it can be a generic, I usually use DOIT as my search argument) and if the bo...

@allocsb Great. Keep an eye on it, the VCC pins are labelled as 5V and connect to an LDO that coverts 5V to 3.3V. If your external is actually only 3....

@josiah430 I'm sorry, am I not speaking clearly? What do you mean exactly, is the USB cable not able to connect to the ESP32? Or are you loading a ske...

@josiah430 And? There are 10 sketches in that video, which is not working for you? It will greatly help if you would post the code here so I can t...

@allocsb External?

@allocsb Do you have 5V or 3.3V on the VCC pin?

Can you provide more information, source code, error messages, wiring diagram would be a start.

@josiah430 Unless you are using some sort of USB based OS, then YES, burn a couple different versions of OS on different TF (micro-SD) cards and off y...

@davee @allocsb This is going to sound confusing. Not being argumentative, just my observations and noting what appear to be inconsistencies. Dave, ...

@davee That would be ironic if the lack of proper grounding saved the Pi from destruction.
