ESP32 C3 Supermini Pinout

I have used many of these boards. Make sure the SuperMini has the ESP32C3FN4 chip which has the on chip SRAM. I mistakenly purchased a batch of Esp32C3 CORE SuperMini which look identical, but do not have the on chip SRAM. These are useless as a mini module and do not work with the IDE or any other platform without additional SRAM. There are many CORE Dev boards I've used that are full size and have the SRAM as a separate chip. I do not understand why the SuperMini version of the CORE exists. I got burnt with them.
