Arduino Pro Mini Atmega328 3,3V 8 MHz (compatible clone)

Arduino Pro Mini Atmega328 3,3V 8 MHz (compatible clone)

Product information:

This Arduino Pro Mini (compatible clone) is intended for semi-permanent installation in objects or exhibitions, for example.
Its small dimensions make it easy to conceal in a housing.

Programming is done with the same software (Arduino IDE) as, for example, the Arduino Uno.

Specifications:

- Microcontroller: ATmega328
- Operating voltage: 3V
- Clock speed: 8MHz
- Input voltage (recommended): 5-12V
- 14 digital input/output pins of which 6 can be used as PWM.
- 8 Analog inputs A0-A7
- Maximum current per I/O pin: 40mA
- Power and status LEDs
- Reset button
- 16KB Flash memory (of which +/- 0.5KB is used by the bootloader)
- EEPROM 512 bytes
- SRAM 1KB
- Protected against overvoltage
- Supplied with separate header pins so you can determine your own configuration
- Auto reset support

Pinouts:

- RAW: For supplying a raw (regulated) voltage (5-12V) to the board.
- VCC: The regulated 3.3 volt supply.
- GND: Ground pins.
- 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.
- 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.
- 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
- I2C: A4 (SDA) and A5 (SCL). Support I2C (TWI) communication using the Wire library.
- 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.

Arduino introduction:
Arduino is an open source computing platform built around Atmel's ATmega328 microcontroller and the Processing software development platform. This platform is intended for hobbyists, performers, artists and anyone interested in creating and designing smart and creative objects that can respond to their environment.

With Arduino it is possible to create devices and objects that respond to their environment using digital and analog input signals. Based on this input, an Arduino circuit can initiate autonomous action by delivering digital and analog output signals. Input can be generated, for example, by switches, light sensors, motion meters, distance meters, temperature sensors, or based on commands from the internet, a radio module or another device with a serial interface. Output signals can, for example, control motors, lights, pumps and screens, but also generate input for another Arduino module.
