Arduino Uno Rev3 SMD

Arduino Micro is based on the same architecture as Arduino Leonardo, but with a smaller form factor, which allows for easy placement on the test plates. That is, it has almost the same functionality but with a much smaller size. And that of size. As we all know, in electronics has meant a lot during the last decades (see example of computers). Developed together with Adafruit, the Leonardo has 20 digital input / output pins of which 7 can be used as PWM outputs and 6 analogue inputs, a 16 MHz crystal oscillator, a micro USB connection, an ICSP header and a reset button. The important thing is also that it comes already equipped with the USB despite its small size because we don't need to install an additional converter.

Arduino Mega 2560 R3  A000067 has been designed with larger and more ambitious projects in mind. It has 54 digital input / output pins (15 of which can be used as PWM outputs), 16 analog inputs, 4 UART (i.e. hardware serial ports). The large number of analog and digital pins, along with larger MEMORY, make the Mega 2560 ideal for devices such as 3D printers and other demanding applications. The Mega 2560 board is compatible with most shields designed for Arduino Uno.

Imagine the simplicity of the Arduino One connected to the communication module. Seems too good to be true, right? That's Arduino One WiFi. Arduino Uno WiFi REV2 (ABX00021) with its integrated IMU (Inertial Measurement Unit) and WiFi is the ideal board to start making your first Internet application from scratch, or to use in the educational field. It has 14 digital input / output pins (5 of which are PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, an accelerometer, an RGB LED, a power connector and an ICSP header.

The Arduino Leonardo is one of the most popular versions of the series, behind only the legendary Uno plate to which it has very similar features (see our comparison below). The board contains a microcontroller ATmega32u4 with the participation of 20 digital inputs/outputs, of which 7 can be used as PWM outputs and 6 analog inputs. The system works with the clock signal with the frequency of 16 MHz, has 32K Flash and 2.5 KB of SRAM RAM.

Arduino UNO is the best board to start your experience with electronics and programming. If this is your first experience with the platform, UNO is the most robust board you can start with. UNO is the most widely used and documented board in the entire Arduino family. Its power ensures ATmega 328p microcontroller, the board is equipped with 14 digital pins, and 6 analog

Arduino Uno R4 WiFi is the original Arduino Uno module with the powerful 32-bit Renesas RA4M1 ARM Cortex M4 ARM Cortex M4 microcontroller. The board is equipped with 256 kB of Flash memory and 32 kB of SRAM, 14 digital I/O, including 6 PWM, 6 ADC and 1 DAC. Popular communication interfaces such as SPI, I2C, UART and CAN are available. It operates with a voltage of 5 V. The ESP32-S3-Mini chip handles WiFi and Bluetooth communication. The Uno R4 WiFi features a 12x8 matrix of addressable red LEDs as well as a Qwiic connector.

Arduino Due is the perfect board for powerful large-scale Arduino projects. This is the only Arduino microcontroller based on the Microchip SAM3X8E with an Arm Cortex-M3® processor. If other basic boards are not enough for your ideas and demands, this one will surely satisfy them. Add to this 54 pins (54 digital input/output pins, 12 analog inputs, 2 DAC, 2 CAN and 4 UARTS) and you have a board that will not stop before any obstacle.

Arduino Nano A000005 is the smaller, friendlier version of Uno's badge. Perfect for IoT applications and for mobile device prototypes. This board is based on the ATmega328 and has a wide range of applications, thanks to its small size and flexibility.
