On Google Sheets I maintain a document with the GPIO pin mappings of the ESP32 MCU and how they are connected on some of the popular modules like:
- DOIT ESP32 DEVKIT V1
- Lolin32
- Lolin32 Lite
- TTGO T-Micro32
- TTGO T-Display
- TTGO VGA32
- ODROID GO
- M5Stack
De color conventions used are kept consistent for all pinouts.

Here are the pinouts of the ESP32 modules made by Espressif (ESP-WROOM-32 and ESP32-WROVER):

Here are the pinouts of the adapter boards for these modules:
