Description:

The ARDUIN0 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), 6 analog inputs, an onboard resonator, a reset button, and holes for mounting pin headers. A six-pin header can be connected to an FTDI cable or Sparkfun breakout board to provide USB power and communication to the board. The ARDUIN0 Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the ARDUIN0 Mini. There are two versions of the Pro Mini. One runs at 3.3V and 8 MHz, the other at 5V and 16 MHz.

Specification:

Power:

The ARDUIN0 Pro Mini can be powered with an FTDI cable or breakout board connected to its six-pin header or with a regulated 3.3V or 5V supply (depending on the model) on the Vcc pin. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin, not VCC.
The power pins are as follows:
RAW: For supplying a raw voltage to the board
VCC: The regulated 3.3 or 5 volt supply
GND: Ground pins

Memory:

The ATmega328 has 32 KB of flash memory for storing code (of which 0.5kB is used for the bootloader). It has 2 KB of SRAM and 1kBs of EEPROM (which can be read and written with the EEPROM library.

Input And Output:

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 ARDUIN0 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, each of which provides 10 bits of resolution (i.e. 1024 different values). Four of them are on the headers on the edge of the board; two (inputs 4 and 5) are on holes in the interior of the board. The analog inputs measure from ground to VCC.
