Fully compatible replacement of the Arduino UNO module with the Atmega328P-PU microcontroller mounted in the socket. It has 14 digital input/output pins (including 6 of them can work in PWM mode).
The Arduino Mega 2560 maple has up to 54 digital inputs/outputs of which 15 as PWM, and 16 analog inputs. The construction of Megi allows the use of shields from Arduino Uno, the tiles are compatible in terms of pins.
Arduino Due is a popular module based on the SAM3x8E microcontroller. It has 54 input/outputs (including 12 of them can work in PWM mode).
Arduino Nano V3.0 with a USB connector (for self -assembly). Universal Mini Arduino module with ATMEGA328P microcontroller and a USB connector. Possibility to use in many microprocessor projects.
Arduino Pro Mini is a plate that is based on the atmega328 microcontroller.The tile has 14 digital inputs/outputs and 8 analog inputs and contains everything you need to quickly start working with the microcontroller.The module does not have soldered pins, thanks to which the user can only solder the pins he will need.
The Arduino Pro Micro system is characterized by small sizes: 33 x 18 mm. Uses the ATMEGA32U4 microcontroller from the AVR family. It is equipped with 12 digital inputs/outputs and 4 analog inputs. The system works with 5.0 V voltages, it is clocked at a clock signal with a frequency of 16 MHz.
Shield I/O allows you to connect Arduino Nano with other Arduino modules.
