The board Arduino Pro Mini strong> - a device based on microcontroller ATmega168. It includes: 14 digital inputs / outputs (of which 6 can be used as PWM outputs), 8 analog inputs, quartz resonator, a reset button and pads for soldering connectors.
Arduino Pro Mini strong> can be supplied:
via cable FTDI;
from the board-converter;
from a regulated power supply 5 V output via Vcc;
from unregulated power output through RAW.
Six-connector can serve both for food and for interaction with the board via USB through FDTI-adapter.
Each of the 14 digital pins on the Pro Mini strong> can work as input or output. The voltage level at the terminals is limited to 5V. The maximum current of 40 mA at the terminals. All findings are associated with the internal pull-up resistor (disconnected by default) the nominal value of 20-50 ohms.
Platform Arduino Pro Mini strong> has several options for opportunities to communicate with a computer, another Arduino, or microcontrollers:
ATmega168 supports serial UART TTL, digital pins 0 (RX) and 1 (TX).
Using the Library SoftwareSerial can create a serial communication on any of the digital outputs Pro Mini strong>.
ATmega168 supports interfaces I2C (TWI) and SPI.
In Arduino Pro Mini strong> enabled Wire library to simplify use of the bus I2C.
The platform is programmed by software Arduino. ATmega168 microcontroller comes with a recorded loader facilitates the recording of new programs without external programmers. Communication takes the original protocol STK500. You can also bypass the bootloader and program the ATmega168 using an external programmer.
The board Arduino Pro Mini strong> is designed for semi-fixed installation in a variety of equipment or installation. Fee specially delivered without soldered connectors that allows the user to solder a wire or connector types required to use at their discretion. By location pins Arduino Mini Pro is compatible Arduino Mini.
