Arduino Pro Mini module is based on the popular Uno. The board contains an ATmega328 microcontroller equipped with 14 digital I/o, 6 of which can be used as PWM outputs (e.g. for motor control) and 8 analog inputs. The system works with the clock signal with the frequency of 8 MHz, working voltage is 3.3 V, 32 KB Flash memory and 2 KB RAM SRAM.


Unlike the Arduino Pro, Arduino Pro Mini version has no connectors, preserving the small size. The user decides which I/O will be needed.


This version works with a voltage of 3.3 V at a frequency of 8 MHz.

In our offer you will also find module Pro Mini 5v / 16 MHz.

For programming the tile, you will need a converter USB - UART.



  • Supply voltage: from a 3.35 V to 12 V
  • Microcontroller: ATmega328
    • Maximum clock frequency: 8 MHz
    • SRAM: 2 KB
    • Flash memory: 32 KB (5 KB is reserved for bootloader)
    • EEPROM: 1 KB
  • Pins I/O: 14
  • PWM channels: 6
  • Number of analog inputs: 8
  • Serial interfaces: UART, SPI, I2C
  • External interruptions
  • Protection from supplying too much current
  • Module is made on the laminate, 0.8 mm thick
  • Mass - below 2 g
  • Dimensions: 33 x 18 mm



If the voltage is higher than 3.3 V, you should connect them to the I/O of RAW, which is connected to stabilizer. VCC is directly connected to the pins of the microcontroller, connecting the voltage which is higher than 3.3 V, may permanently damage the system.



Creating and uploading software, allows free environment supplied by the manufacturer. This tile doesn't have a system that controls USB interface. Therefore, the adapter UART - USB is necessary for programming.
