[버섯][Arduino] 아두이노 프로 미니(Arduino Pro mini)

키워드 : 아두이노 , Arduino , 아두이노 프로 미니 , Arduino Pro Mini , 


안녕하세요 버섯돌이 유재성입니다.

STM32관련 보드를 몇 개 구매하기는 했지만 학습을 차일피일 미루다보니

학습하기 무난하고 사이즈가 작아서 활용도가 많을것같은 아두이노 프로 미니를 장만했습니다.^^

역시나 기초가없으니 대부분의 예제가 Arduino UNO 라서 불필요한 시간 손실을 줄이기 위해 우노도 하나 장만했네요.^^


3.3v를 사용하는 모델과 5v를 사용하는 2가지 모델이 존재하는데 저는 5v 모델의 호환 제품을 구매했습니다.^^



크기도 상당히 작고 가격도 저렴해서 예전에 구매했던 아카데미 탱크에 사용하기 딱 좋을것 같습니다.*^^*



상태가 안 좋은 인두기로 열심히 납 땜할 생각을하니 순간 아찔하군요...



최종 완성된 모습입니다.



대략 위와같이 생겼습니다.

크기가 작고 아두이노 예제들이 많아서 처음 사용함에도  사용하기에 편하더군요.*^^*

Summary

Microcontroller ATmega168

Operating Voltage 3.3V or 5V (depending on model)

Input Voltage 3.35 -12 V (3.3V model) or 5 - 12 V (5V model)

Digital I/O Pins 14 (of which 6 provide PWM output)

Analog Input Pins 8

DC Current per I/O Pin 40 mA

Flash Memory 16 KB (of which 2 KB used by bootloader)

SRAM 1 KB

EEPROM 512 bytes

Clock Speed 8 MHz (3.3V model) or 16 MHz (5V model)


Power

The Arduino Pro Mini can be powered with an FTDI cable or breakout board connected to its six pin header, or with a regulated 3.3V 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 on 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 ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader). It has 1 KB of SRAM and 512 bytes 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 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, each of which provide 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) on holes in the interior of the board. The analog inputs measure from ground to VCC. Additionally, some pins have specialized functionality:

I2C: A4 (SDA) and A5 (SCL). Support I2C (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.
