This is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE it is a great way to jump into electronics, or perfect for when an Arduino is too big or too much. Features : -Support for the Arduino IDE 1.0 (OSX/Win/Linux). -Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection). -On-board 500ma 5V Regulator. -Built-in USB. -6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB). -8k Flash Memory (about 6k after bootloader). -I2C and SPI (vis USI). -PWM on 3 pins (more possible with Software PWM). -ADC on 4 pins. -Power LED and Test/Status LED.

This development board uses the ATmega48 microcontroller for convenient interfacing with the NRF24L01 module. It also features an I2C communication interface that can be used for communication with other microcontrollers such as Arduino or for connecting other peripherals directly to this board. This module comes programmed with an I2C to SPI bridge which implements a convenient RF communication solution. With this module, users do not need to understand the NRF24L01 communication protocol which makes the building of NRF24L01 wireless application easier. This improves the efficiency of the project development process. This module is perfect for robots, remote controls, and remote sensing applications. Specifications Operating Voltage: 5 V (No short-circuit protection) Transfer Rate: 50 Bytes/second I2C/TWI Address: 0x47 (decimal 35) NRF24L01 Address: 0x34, 0x43, 0x10, 0x01, (from low to high)

he Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.

Features :
- Ready to plug & play.
- It can connect to various modules like sensors, servos, relays, buttons, potentiometers
- Each functional module has buckled port with VCC, GND and Output, which has corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking.

This is Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It’s a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage , lack of connectors, and USB off board.

Arduino Nano is a surface mount breadboard embedded version with integrated USB. It is a smallest, complete, and breadboard friendly. It has everything that Diecimila/Duemilanove has (electrically) with more analog input pins and onboard 5V AREF jumper. Physically, it is missing power jack. The Nano is automatically sense and switch to the higher potential source of power, there is no need for the power select jumper. Nano’s got the breadboard-ability of the Boarduino and the Mini USB with smaller footprint than either, so users have more breadboard space. It’s got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other). This new version 3.0 comes with ATMEGA328 which offer more programming and data memory space. It is two layers. That make it easier to hack and more affordable.

The Mega 2560 is a microcontroller board based on the ATmega 2560. It has 54 digital input/output pins (of which 15 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. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards.

The Leonardo is Arduino’s first development board to use one microcontroller with built-in USB. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol! It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
