There are lots of resouces out there on how to build the hardware for an iSpindle so I will not go into details on that part. Here are two of my builds using the iSpindle PCB v4.

It's possible to use this PCB and mount an ESP32 on top of that. It must be an pin compatible ESP32 and the one I used was called *ESP32 d1 mini*. Since this is the same width as the PCB you need to 
mount it really close to the PCB in order for it to fit in the PET tube/container. I also had to smooth the edge of the ESP32 in order for it to fit. 

I would suggest that you try how it fits into the PET tube before soldering it to the PCB. Make sure that the battery is attached since this will be a really tight fit.
