5V.The regulated power supply used to power the microcontroller and other components on the board. This can come either from VIN via an on-board regulator, or be supplied by USB or another regulated 5V supply.
The board can operate on an external supply from 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range ...
3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA. GND. Ground pins. IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the...
3) Landing pad for regulator and caps tied to RAW input pin. 4) FTDI connection on the end. 5) 2 rows of1 9 pins (one row on each side) breaking out all usable pins. Pin rows are spread 9 pins wide. 6) ISP pins are not brought out in 6 pin config but on one port/edge to...

volt boards are powered by a 5-volt power supply(for example, through the USB port), but a voltage regulator converts it to 3.3 volts before it reaches the board’s 3.3-volt electronics. This means that it is not unusual to see a 5-volt power supply pin on a board whose input and...
The only difference is that feeding the Arduino Pro Mini I had to use an external regulator, because the inside is not enough to drive the servo. But let’s get to the list of materials needed: 1 – An Arduino UNO board (or any other compatible) 2 – Two 20K LDR photoresistors (...

ATmega32u4 has built﹏ USB communication, eliminating the need for an external USB o〆rial converter. This allows the Leonardo ETH to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behaviour...
