Pinouts
There's a lot jam-packed into this shield! Let's take a look at what we've got going on.
Power Pins
GND - Common power/logic ground.
3V - this is the output from the 3.3V regulator. The regulator can supply 500mA peak but half of that
is drawn by the ESP32, and it's a fairly power-hungry chip.
5V - This is the input to the regulator
