Please look at supporting the Sparkfun Micomod esp32 processor board.

From https://www.sparkfun.com/products/16781 :

ESP32 General Features:

128mbit/16MB flash storage

I think I got it working?

Using the board config URL from the SparkFun ESP32 MicroMod software setup guide, I took the .tar.bz2 from that JSON file and did two things:

1. Copied the variants/esp32micromod to ~/.platformio/packages/framework-arduinoespressif32/variants so that I had the pins_arduino.h file
2. Forked platformio/platform-espressif32 and added the esp32micromod.json to the boards folder

Then once I set up my platformio.ini file like so:

[env:esp32micromod]
platform = https://github.com/seanhagen/platform-espressif32.git#add-sparkfun-esp32-micromod
board = esp32micromod
framework = arduino

It compiles and uploads and runs!

I can't find the repo that pio downloads when it downloads the framework-arduinoespressif32 framework, so I wasn't able to fork that to add esp32micromod/pins_arduino.h to it, but I have created a pr for the platformio-espressif32 repo to add the JSON
