Hi folks
these boards are pretty nifty, acessability Is great, just download the ide flash via usb and your set to go.
They are a vape, the aegis x.
the microcontroller that allows all this is from Panasonic owned nuvaton whom have released they’re own ide for programming but also a way to easily convert to arduino 1.5.8. The chip can function without a crystal, has multiple clocks and has a Pwm frequency into the 140mhz range.
I found the idea of vaporising water with a peizo disc directly from a chip that dosnt require a crystal every 60 seconds pretty weird.
But jokes Aside there is a huge amount of potential in a hefty power distribution board like this.
here’s the data sheet for the microcontroller for those intrested:

what I wanted to ask is could anyone help with an electronic component search engine or a nod in the right direction, maybe your knowledge could make a difference as I search for the data sheets and to identity so many little black chips amongst a sea of diodes capacitors and resistors.
if I knew what I was looking at researching and experimenting in how programming is achieved would be a fun and interesting project.

A few more pictures, iPad Pro m1 made a great microscope.

 

The pcb markings will tell you what each component is , R resistor, D diode , C capacitor, L inductor, Q transistor , U chip.

thank you for your input, already Makes more sense. I can see a few chips. I’ve gotten as far as the smd database but haven’t had any luck with these chips. Unless I’m missing something obvious.
depopulating a board to trace all the pins Should Be lot easier with the provided markings too

The two identical chips behind the mosfets are mosfet drivers (2 each and one mosfet extra to control the buck converter) here is the data sheet.

The mosfet , qn3110 is a 30v fast switching mosfet. The additional numbers are manufacturing information such as date, well according to the data sheet:

How Do you even begin to research 4 numbers on a black square anyone help?

 

Some of these parts might be in house specialty components. I recently watched a video on how to do this. I believe it was on YouTube and titled EEVblog 1475.

I checked it out, I have been researching this stuff, things like smd database can Help you track things down. They are pretty Neat but when made in china they can switch out parts (think arduino uno)and use manufacturers based there that are hard to track down. I haven’t had much luck but have speculated on functionality. its surrounded by capacators and inductors, it’s probbably something To keep the voltage constant as the batteries drop in charge and voltage

 

It's such a weird shape. Could it be an inductor? Or a fuse?

The inductors are the metal squares and fuses are numbered and mostly small, the board is also marked out which helps identify components, for example a D is a diode

 

also as a correction here is the correct microcontroller

a sight to behold, a grail amongst microcontrollers, a temp sensor? lovely features.
