Are they really as good as arduino's?
Induino-X http://induino.com/wiki/index.php?title=InduinoInduino-X Made In India good as any arudino you can lay your hands on. On top of this, it has a host of on-board devices to make your learning easy. it has 3 leds, 3 buttons, 1 tsop, 1 IR led, 1 ldr, 1 ds1307 RTC & 1 RGB led1. RGB Tri-colour LEDRed : Pin 5 (PWM)Green : Pin 6 (PWM)Blue : Pin 3 (PWM)2. Tactile switchesSwitch 1 : Pin 7Switch 2 : Pin 8Switch 3 : Pin 93. LEDs (Colours of the LEDs may vary depending upon the version you have)LED 1 (red) : Pin 11 (PWM)LED 2 (blue) : Pin 12LED 3 (white) : Pin 134. IR LED : Pin 14 (Analog 0)5. TSOP : Pin 15 (Analog 1)6. LDR : Pin 17 (Analog 3)7. DS1307 (RTC)SDA : Pin 18 (Analog 4)SCL : Pin 19 (Analog 5)I m From India !!Avadhut ;)

The 'Freeduino SB', manufactured and sold as a mini-kit by Solarbotics Ltd.. The 'Cosmo Black Star', manufactured and sold by JT5. The CraftDuino, manufactured and sold by RoboCraft Team. The 'Freeduino MaxSerial', a board with a standard DE-9 serial port. It was manufactured and sold assembled or as a kit by Fundamental Logic until May 2010. The 'Freeduino Through-Hole', a board that avoids surface-mount soldering, manufactured and sold as a kit by NKC Electronics. The 'Illuminato Genesis', a board that uses an ATmega644 instead of an ATmega168. This provides 64 kB of flash, 4 kB of RAM and 42 general I/O pins. Hardware and firmware are open source. The 'metaboard', a board that is designed to have a very low complexity and thus a very low price. Hardware and firmware are open source. It was developed by Metalab, a hackerspace in Vienna. The 'Seeeduino', derived from the Diecimila. The 'eJackino', kit by CQ publisher in Japan. Similar to Seeeduino, eJackino can use Universal boards as Shields. On back side, there is a "Akihabara station" silk, just like Italia on Arduino. The 'Japanino' is a kit by Otonano Kagaku publisher in Japan. The board an a POV kit was included in Vol. 27 of the eponymous series. An ATmega168 powers it. It is unique in having a regular size USB A connector. The 'Wiseduino' is an Arduino-compatible microcontroller board, which includes a DS1307 real-time clock (RTC) with backup battery, a 24LC256 EEPROM chip and a connector for XBee adapter for wireless communication. The 'TwentyTen' is an Arduino-compatible microcontroller board, based on the Duemilanove, with some improvements, including a prototyping area, rearranged LEDs, mini-USB connector, and altered pin 13 circuitry so that the LED and resistor do not interfere with pin function when acting as an input. The 'Volksduino' is a low cost, high power, shield compatible, complete Arduino-compatible board kit. Based on the Duemilanove, it comes with a 5 V / 1 A voltage regulator and has an option for a 3.3 V regulator. The Volksduino was designed by Applied Platonics to have a low component count and to be "easy for anyone of any age to put together". The 'ZArdino' is a South African Arduino-compatible board derived from the Duemilanove, features mostly through hole construction with the exception of the SMD FT232RL IC, power selection switches, option for a phoenix power connector instead of DC jack, extra I/O pads for using Veroboard as shields, designed to be easy to construct in countries where exotic components are hard to find. The 'Zigduino', is an Arduino using the ATmega128RFA1 to integrate Zigbee (IEEE 802.15.4). It can be used with other 802.15.4 network standards as well as ZigBee. The board is the same shape as the Duemilanove and includes an external RPSMA jack on the side of the board opposite the power jack. It is compatible with shields that work with other 3.3 V boards. The 'InduinoX' is a low cost Arduino clone using the ATmega168/ATmega 328/ATmega 8 and designed for prototyping. It includes on board peripherals such as an RGB LED, switches, IR Tx/Rx and DS1307(RTC). It is developed and marketed by Simple Labs. The 'Luigino328 is an Arduino with ATmega328. It has an improved automatic voltage selector and resolves the problems during programming caused by shields that uses the serial port thanks to the Automatic Serial Port Selector feature. The '1000Pads Luigino' is a minimalistic version of Arduino: small, without serial converter and available as kit, board only or assembled. Warning: this board hasn't the same footprint of Arduino since is smaller. The 'Brasuíno' is an Arduino-compatible microcontroller board, based on the Uno, with some improvements, including rearranged LEDs and reset button, mini-USB connector, and altered pin 13 circuitry so that the LED and resistor do not interfere with pin function when acting as an input. The Brasuíno was designed using KiCAD, and is licensed as GPLv2. Designed and manufactured by Holoscópio, from Brazil. The "Diavolino" - another Arduino compatible board from Evil Mad Scientist Laboratories.These are the arduino clones and they all have +'s and -'s for example take the netduino it is compatible with.NET programming, but it quite a bit more expensive than the arduino...so if you can tell what you would use it for then we could decide that best arduino clone or the arduino board for you!
Depends. Physical layout is often somewhat different, which may be an advantage or disadvantage, especially if you want to use some of the "shield" plug-in modules. Support circuitry may be different -- read the specs. You may have to do more assembly.Outside of those, there's no particular reason they _have_to_ differ.
