Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world.
Arduino Uno R3 Compatible – Atmega 328 DIP
This is the Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.
Arduino Pro Mini 328 – 3.3V/8MHz
It’s blue! It’s thin (0.8mm)! It’s the Arduino Pro Mini 328! This is a 3.3V Arduino running the 8MHz bootloader . The Arduino Pro Mini 328 doesn’t come with connectors populated so you can solder in any connector or wire with any orientation you need. The Arduino Pro series is meant for users that understand the limitations of system voltage (3.3V), lack of connectors, and USB off board.
Arduino Pro Mini 328 – 5V/16MHz
It’s blue! It’s thin (0.8mm)! It’s the Arduino Pro Mini 328! SparkFun’s minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader (select ‘Arduino Duemilanove w/ 328’ within the Arduino software). The Arduino Pro Mini doesn’t come with connectors populated so you can solder in any connector or wire with any orientation you need. The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.
Arduino Lillypad Big
The LilyPad Arduino 328 Main Board is an Arduino-programmed microcontroller designed to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight, round package designed to minimize snagging and profile, with wide tabs that can be sewn down and connected with conductive thread.
Arduino Compatible Nano V4
The Arduino Nano V4 is a small, complete, and breadboard-friendly board based on the ATmega328. It differs from our other Nano V3 board in using a Prolific PL2303 chipset instead of the FTDI chip in the Nano V3.
Arduino Compatible Mega 2560
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
