I am working my way through Bill's introduction to ESP32 video on Youtube. I have made it through all of the examples up until the Repeat Timer segment. This segment requires a pin 0 which my ESP32 does not have.

Here's a link to the pinout for my module. https://esp32.com/viewtopic.php?t=9875

My question is I am looking for another pin 0 equivalent on this module?

Also, the pins are too wide for a breadboard so I had to muck around to get it situated on the breadboard. Life if full of challenges. 🤔

From the pinout diagram, it looks like GPIO0 shares the same pin as GPIO36.

A good reference on ESP32 GPIO pins is on Random Nerd Tutorials.

Sometimes it's easier to use two breadboards side-by-side for those huge modules!

You can put stackable headers on your breadboard and the make all of the connections under the ESP32 module before installing it in the headers.  You could also cut a breadboard in half and use the ESP32 board to space the two pieces the proper distance apart before gluing them down.  With a 3D printer, you can print a tray to hold the two breadboard halves.

HTH,
