TinyPICO: A small and powerful ESP32 development board (including source code, schematics, PCB, etc.)

There are many ESP32 development boards on the market, but they all require you to compromise on one or more features. Some don't have onboard battery management, some do but not the low deep sleep current. Others have nice low power modes, but are large and not breadboard friendly, and none of them have extra RAM unless you opt for the more expensive and larger WROVER powered board. We’re just not happy with the status quo – we want to have our cake and eat it too! So we designed the world's smallest no-compromise ESP32 board and then went a step further by giving it 4 MB of additional RAM, an onboard RGB LED, and a 700 mA 3.3 V regulator.
