Intel Edison development platform is designed to lower the barriers to entry for a range of inventors, researchers and consumer product designers to rapidly prototype and produce “Internet of Things”(IoT) and wearable computing products. Supports Arduino Sketch, Linux, Wi-Fi, and Bluetooth. CPU to a 22 nm Silvermont dual-core Intel Atom CPU.
The 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 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 FRDM-KL43Z is development platform for Kinetis. It has on board capacitive touch slider, Accelerometer and magnetometer all of it in ultra low cost price and if you are tired using external power supply, here you can also find coin pin and USB as power supply.
Arduino YÚN is the perfect board to use when designing connected devices and, more in general, Internet of Things projects. It combines the power of Linux with the ease of use of Arduino. It has microcontroller board based on the ATmega32u4 and the Atheros AR9331.The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot. A very handy choice for Developers.
AM3359 Industrial Communications Engine
Its a bit costly than others , but you’re paying for a powerful platform centered around the Sitara AM335x ARM Cortex A8 Processor. That means plenty of processing power(and it runs Windows) and, more importantly, has an integrated Programmable Real-time Unit (PRU), that makes this board a start for real-time communication technologies. Add to that an on-board OLED display and incredible power performance, and you’ve got yourself a top class developer board.
