O Arduino tem muitas variantes. Uns podem ser meros clones, mas outros podem destacar-se pelo baixo preço ou pelas pequenas dimensões. Cabe ao utilizador saber escolher na hora da compra.

Preparem-se para um grande scroll-down!

Para celebrar o 3º Aniversário do Hardware Open-Source, a MAKE deixou no seu blog uma lista das plataformas baseadas no Arduino.

Arduino Duemilanove

• Microcontroller ATmega168
• Operating Voltage 5V
• Input Voltage (recommended) 7-12V
• Input Voltage (limits) 6-20V
• Digital I/O Pins 14 (of which 6 provide PWM output)
• Analog Input Pins 6
• DC Current per I/O Pin 40 mA
• DC Current for 3.3V Pin 50 mA
• Flash Memory 16 KB (of which 2 KB used by bootloader)
• SRAM 1 KB
• EEPROM 512 bytes
• Clock Speed 16 MHz

LilyPad Pro Kit

• LilyPad Mainboard
• LilyPad Power Supply
• LilyPad USB Link
• Mini USB Cable

Arduino Nano

• Automatic reset during program download
• Power OK blue LED on the bottom
• Green (TX), red (RX) and orange (L) LED
• +5V to AREF jumper
• Auto sensing/switching power input
• Small mini-B USB for programming and serial monitor
• ICSP header for direct program download
• Power OK blue LED on the bottom
• Standard 0.1″ spacing DIP (breadboard friendly)
• Manual reset switch

Arduino Pro

• ATmega168V running at 8MHz external resonator
• Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, Accelerometers, sensors, etc)
• USB connection off board
• 3.3V regulator
• Reverse polarity protected
• DC input 3.3V up to 12V
• Resettable fuse prevents damage to board in case of short
• Power select switch acts as on/off switch

Bare Bones Arduino

• Mesmas funcionalidades do Arduino
• Inclui redução de ruído (Não presente no Duemilanove)
• Preparada para integrar numa breadboard

Sanguino

• atmega644P core
• 32 total general purpose I/O pins (some are multipurpose)
• 8 analog pins
• 6 PWM pins
• 64K flash memory
• 4K RAM
• 2K EEPROM
• completely through-hole construction
• breadboard compatible
• 100% open source
• compatible with Arduino 0012 with minimal hacking

Seeeduino

• Duplicate digital IO to 100mil grid for prototype board compatibility.
• Shrink componets height below female headers.
• Change Type-B USB port to Mini USB.
• Replace 3.5mm DC power Jack to battery 2 Pin plug.
• Reset and power indicator near RST button.
• Auto-reset selection.
• 3.3V Operating Voltage selection.
• Pin out UART for FTDI232 bit-bang operation.
• Pin out 2 extra ADC.
• Optional capacitor for improving 3.3V output performance.
• Pin out for I2C and sensors

Boarduino

• Designed to plug into a breadboard for easy prototyping
• Petite size, only 3″ x 0.8″ (75mm x 20mm)
• All ’standard’ pins are brought out – Digital 0 thru 13, Analog 0 thru 5, ARef, 5V, Ground, Vin and Reset
• Chip comes preprogrammed with a “no-wait” Arduino bootloader (Read more here)
• 2 LEDs, green power and red “pin 13″ just like the Arduino Diecimila
• Available as a low cost kit with standard parts, so its never out of stock
• All through-hole parts are easy to solder
• Reset button
• ATmega168, running at 16.00 MHz, just like the lastest Arduino, the Diecimila
• 6-pin standard ICSP header
• Standard 2.1mm DC jack (just like the original) with 5V regulator to run on 7V-17V power
• 1N4001 diode protects against using incorrect wall adapter
• 6-pin header at the end for a USB-TTL cable
• Auto-reset capability when used with a USB-TTL cable

Freeduino

• Exactamente o mesmo que o original… As mesmas funções e dimensões

iDuino

• For use with electronics breadboards
• Can be powered via USB
• Uses standard 5mm LEDs as status indicators.
