Controller board for flashing ESP32

I wanted to know what ESP32, there are sizes and where they can be ordered. for my project I need to place the board in the holes of the tube 16x16 and that from the tube came out input type c. for power. perhaps you can advise me something. if such boards do not exist then tell me where you can order a case to place the board, preferably in a cylindrical base where on one side will go the cord for power and the other output with a usb cord

The smallest ESP32 I have is a Atom S3 Lite, but it’s still significantly larger than you specs (24x24x9.5mm). Not cylindrical, but on my end I fit it easily in 25mm diameter hole. The advantage is that it comes with a case :).

Be aware that it’s not a well supported device yet and you should look at this thread M5stack Atom S3 Lite (which compile settings?) - Totally freaking out after 3 night/days - #10 by dr1rrb
