There is a small RGB LED to the left of the ESP32. These RGB
LEDs are available in the Arduino and CircuitPython libraries if
you'd like to PWM them for a visual alert. They're connected
to the ESP32's pins 26 (Red), 25 (Green), and 27 (Blue).
Prototyping Area
We have a big grid of prototyping holes and power rails if you
want to make some custom circuitry!
