5v arduino pro micro serial#

On-Board micro-USB connector for programming.

If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin on not VCC.

There is a voltage regulator on board so it can accept voltage up to 12VDC. The lower system voltage also has its advantages, though, like ease of use with many common 5V sensors.

This is the 5V version so, as always, keep in mind the limits of system voltage and so forth. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere.

5v arduino pro micro serial#

The Arduino Pro Mini connected to (and powered by) an FTDI TTL-232R-3V3 USB - TTL Level Serial Converter Cable. This tiny little board does all of the neat-o Arduino tricks that you’re familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. For the 5V versions of the Arduino Pro Mini, select Arduino Duemilanove or Nano w/ ATmega328P or Arduino Diecimila, Duemilanove, or Nano w/ ATmega168. The UVCC (USB power/VBUS) goes through a fuse and diode before it meets with the RAW pin and into the regulator. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface. Looking at the schematics from Sparkfun, the Arduino Pro Micro can have either a 5V or 3.3V regulator on it, the jumper can just bypass this regulator as previously stated. The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board.

The ATmega32U4 also allows for serial (CDC) communication over USB and appears as a virtual com port to software on the computer.
