|=======================
|Pin Category|Pin Name|Details
|Power|Vin, 3.3V, 5V, GND|
* Vin: Input voltage to Arduino when using an external power source.
* 5V: Regulated power supply used to power microcontroller and other components on the board.
* 3.3V: 3.3V supply generated by on-board voltage regulator. Maximum current draw is 50mA.
* GND: ground pins.
|Reset|Reset|
