    This Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 Analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. A six-pin header provides the connection to a TTL to USB converter allowing programming the Arduino Mini Pro using a computer.
    The Pro Mini runs at 5V and 16 MHz. This one on offer here is the 5V and 16 MHz version.
    it needs a Serial converter that supports Auto rest (DTR)

    Summary
    Microcontroller:- ATmega328P
    Operating Voltage:- 5V (depending on model)
    Input Voltage:- 5 - 12 V ( If use 5V, input 5V to Vcc, if used above 5V, input to RAW pin)
    Digital I/O Pins: *14 Digital pins label as RXI, TXO, 2 to 13: (of which 6 provide PWM output, which is pin 3, 5, 6, 9, 10, and 11)
    *8 Analog Input Pin: (label as A0, A1, A2, A3 and A4, A5, A6, A7)
    DC Current per I/O Pin allowed 40 mA, but the max total allowed 150mA for the sum of all pins.
    Flash Memory 32KB
    SRAM:- 2 KByte
    EEPROM:- 1KByte
    Clock Speed:- 16 MHz 

    Input / Output Pins: Each of the 14 digital pins on the Pro Mini can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 3.3 or 5 volts (depending on the model). Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions:

    Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the TX-0 and RX-1 pins of the six-pin header.
    External Interrupts 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.

    PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.

    SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.

    LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
    The Pro Mini has 8 analog inputs, label as A0, A1, A2, A3, A4, A5, A6, and A7, each of which provides 10 bits of resolution (i.e. 1024 different values). 
    I2C: A4 (SDA) and A5 (SCL). Support I2C (TWI) communication using the Wire library.

    Reset Pin:- Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board.

    Communication: The Arduino Pro Mini provides UART TTL serial communication, which is available on digital pins 0 (RX) and 1 (TX). The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board via a USB connection.
    A SoftwareSerial library allows for serial communication on any of the Pro Mini's digital pins.
    The Arduino Pro Mini also supports I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify the use of the I2C bus.
    Programming: The Arduino Pro Mini can be programmed with the Arduino software through a USB to TTL serial converter connected to the Arduino Pro Mini 6 header pin side. Only 5 lines need to be connected because the GND pin repeated.
    This Arduino Pro Mini 6 header pin side for programming has the following pin label:-
    DTR (labeled on the reverse side of the board)
    TXO
    RXI
    VCC
    GND
    GND (Another repeated GND pin, labeled on the reverse side of the board)
    Connection for programming with a CP2104 USB TTL serial Converter is as following:-
    CP2104 <------>Pro Mini
    DTR<------>DTR
    RXD<------>TXO
    TXD<------>RXI
    5V<------>VCC
    GND<------>GND
    Total 5 line connection.
    Pro Mini side another GND pin no need to connect. (there are two GND pin, connected one is enough)
