Does this have a 3.3v regulator on board? Can it be fed with 5v & be regulated to 3.3v for its operation? Looks like it does. I just want to be sure.

Yes, I was able to successfully connect these Micro SD Cards to the 5V source of Arduino Nano boards for various applications. Mine all work fine! They have been in use continuously for weeks at a time to store data for temperature/humidity, voltage, and GPS logging devices with no issues.

Will this work with an Arduino Nano?

It does, but I had to use 5V for VCC, and only certain pins will work for the other connections.

Will this work with a ESP32?

Yes. It works well in my interface card

What file systems are supported?

It depends on you operating system. The module (MicroSD Card Adapter) is a Micro SD card reader module for reading and writing through the file system and the SPI interface driver Installed on the arduino board.
