There is a voltage regulator on board, so it can accept up to 12V DC.

The Arduino Pro Micro 5V 16M Leonardo Micro is a microcontroller board based on the ATmega32U4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button.

It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.

The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor.

This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

If you supply an unstable power supply board, be sure to connect to the “RAW”, not on the VCC pin. It has also added a PTC fuse and diode protection to the power circuit and to correct the RX and LED TX circuits.

Technical Features :

1. ATMEGA32U4 running in 5V / 16MHz
2. Support Arduino IDE V1.0.1
3. Micro USB interface programming on the board
4. Four 10-bit ADC pin
5. 12 digital I / O (5 PWM capability)
6. Rx and Tx hardware serial connection.

The Nano Board R3 with CH340 chip without USB Cable is vital for your small project where you don’t need much of a pin-outs but the small size is very important to make it look good.

This Nano equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano.

The Arduino Nano R3 CH340 Soldered is a small, complete, and breadboard-friendly board based on the ATmega328 (Nano R3).

It has more or less the same functionality of the Uno but in a different package.

It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.

The Nano can be power via the mini-USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27).

The power source is automatically selected to the highest voltage source.

The size of Nano CH340 Chip is only 43 mm x 18 mm; it comes with 6 PWM I/O from the total of 14 digitals I/O, 8 analog inputs, 16Mhz clock speed and 32kB of flash memory.
