mbed is a tool for rapid prototyping with microcontrollers.
Microcontrollers are getting cheaper, more powerful and more flexible, but there remains a barrier to a host of new applications; someone has to build the first prototype! With mbed, we've focused on getting you there as quickly as possible.
The mbed Compiler lets you write programs in C/C++, and then compile and download them to run on the mbed microcontroller. It's all online, so you don't need to be a sys-admin to start. In fact, you don't have to install or setup anything to get started.
The FRDM-KL25Z is an ultra-low-cost development platform enabled by Kinetis L Series KL1x and KL2x MCUs families built on ARM® Cortex™-M0+ processor. Features include easy access to MCU I/O, battery-ready, low-power operation, a standard-based form factor with expansion board options and a built-in debug interface for flash programming and run-control. The FRDM-KL25Z is supported by a range of Freescale and third-party development software.
The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet). It is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.
Keil (an ARM company) offers starter kits based on the ARM Cortex-M3-based STMicroelectronics STM32F103 microcontroller. These kits include an evaluation board, a Keil ULINK-ME USB-JTAG interface, as well as the RealView MDK-ARM evaluation software tools.
