It’s a little ESP32 Board. Perfect for controlling or sensing stuff in the real world and sync it to the internet! Despite that it features the ESP32 WROVER Module. This means it got 4MB FLASH and 4MB RAM. That’s an absolute incredible amount of RAM. I honestly have no clue for what I will ever need 4MB in my embedded Projects.

Why did you make it?

I wanted a small ESP32 Board with the pSRAM and which works and doesn’t eat your whole time to get it working and find it’s issues and quirks.

I’ve used the CP2102 Serial converter because this is the one, which works the best way to program the ESP32. Even Espressif uses this serial converter on their own dev boards.

What makes it special?

It’s propably the smallest ESP32 Board with pSRAM. Despite the size it’s ideal for battery operation. It uses under 200uA in Deep Sleep mode!
