It simply consists of an ATMega48 and ATMega88 an ATMega8 and a couple of. PDFPower. The Arduino Pro Mini can be powered with an FTDI cable or breakout board connected to its six pin header, or with a regulated 3. V or 5. V supply depending on the model on the Vcc pin. There is a voltage regulator on board so it can accept voltage up to 1. VDC. If youre supplying unregulated power to the board, be sure to connect to the RAW pin on not VCC. The power pins are as follows RAW For supplying a raw voltage to the board. VCC The regulated 3. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560.

The ATmega. 32. 8 has 3. B of flash memory for storing code of which 0. B is used for the bootloader. It has 2 k. B of SRAM and 1k. Bs of EEPROM which can be read and written with the EEPROM library. Input and Output. Each of the 1. 4 digital pins on the Pro Mini can be used as an input or output, using pin. Mode,digital. Write, and digital. Read functions. They operate at 3. Each pin can provide or receive a maximum of 4. A and has an internal pull up resistor disconnected by default of 2. Ohms. 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 attach. Interrupt function for details. PWM 3, 5, 6, 9, 1.

LED 1. 3.  There is a built in LED connected to digital pin 1. When the pin is HIGH value, the LED is on, when the pin is LOW, its off. The Pro Mini has 8 analog inputs, each of which provide 1. Four of them are on the headers on the edge of the board two inputs 4 and 5 on holes in the interior of the board. The analog inputs measure from ground to VCC. Additionally, some pins have specialized functionality I2. C A4 SDA and A5 SCL. Support I2. C TWI communication using the Wire library. There is another pin on the board Reset. 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 has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega. 32. 8 provides UART TTL serial communication, which is available on digital pins 0 RX and 1 TX. Install Firefox Using Yum Linux Update there. 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 Software. Serial library allows for serial communication on any of the Pro Minis digital pins. The ATmega. I2. C TWI and SPI communication. The Arduino software includes a Wire library to simplify use of the I2. C bus see the reference for details. To use the SPI communication, please see the ATmega. Programming. The Arduino Pro Mini can be programmed with the Arduino software download. For details, see the reference and tutorials. The ATmega. Arduino Pro Mini comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK5. C header files.  You can also bypass the bootloader and program the ATmega. Automatic Software Reset. Rather then requiring a physical press of the reset button before an upload, the Arduino Pro Mini is designed in a way that allows it to be reset by software running on a connected computer. One of the pins on the six pin header is connected to the reset line of the ATmega. F capacitor. This pin connects to one of the hardware flow control lines of the USB to serial convertor connected to the header RTS when using an FTDI cable, DTR when using the Sparkfun breakout board. When this line is asserted taken low, the reset line drops long enough to reset the chip. The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of the reset line can be well coordinated with the start of the upload. This setup has other implications. When the Pro Mini is connected to either a computer running Mac OS X or Linux, it resets each time a connection is made to it from software via USB. For the following half second or so, the bootloader is running on the Pro. While it is programmed to ignore malformed data i. If a sketch running on the board receives one time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.
