Mock up

[Mark Grennan]

I'd like to mock up a ESP32 for for code development.

I'd like to know what pins the SDCard reader ( CS MOS1 CLK, and MIS0) connect to as well as the PSRAM.  

Thank you.

Mark,

If you'd like similar hardware for your own development purposes, look into an ESP32-based device like the m5Stack Core2; it has a microSD slot, 16MB flash, 8MB PSRAM, and a bunch of other features for around $50-ish

If you want to build your own microSD and PSRAM add-ons to an ESP32 board, there are very standard ways of hooking them up and you can easily Google "esp32 psram/microsd schematic" to get multiple examples that all show almost identical schematics. Note that some boards/modules will not expose all necessary signal lines and you'll have to choose one where the proper lines are available.
