Arduino Pro Mini is based on the popular Uno module. The board containsan Atmega328 microcontroller, equipped with 14 digital I / O, 6 of which can be used as PWM outputs (eg for motor control) and 8 analog inputs.The clock is clocked at 16 MHz, works with 5.0 V, has 32 kB of Flash memory and 2 kB of SRAM.
Power supply: from 5 V to 12 V
The maximum clock frequency is 16 MHz
SRAM memory: 2 kB
Flash memory: 32 kB (5 kB reserved for the bootloader)
EEPROM memory: 1 kB
Pins I / O: 14
PWM channels: 6
Number of analog inputs: 8
Serial interfaces: UART, SPI, I2C
Protection against excessive current flow
The module is made on a laminate with a thickness of 0.8 mm
Weight below 2 g
Dimensions: 33 x 18 mm
The VCC is connected directly to the microcontroller's pins, connecting a voltage higher than 5.0 V can permanently damage the system.
Software creation and uploading is made possible by the free environment provided by the manufacturer.This board does not have a USB interface.Therefore,a UART - USB Adapteris required for programming .
