Rapid Prototyping for general microcontroller applications, USB and 32-bit ARM® Cortex™-M0+ based designs

Overview¶

The FRDM-KL25Z has been designed by Freescale for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M0+ and the power of USB Host and Device. It is packaged as a development board with connectors to break out to strip board and breadboard, and includes a built-in USB FLASH programmer.

It is based on the Freescale KL25Z, with a 32-bit ARM Cortex-M0+ core running at 48MHz. It includes 128KB FLASH, 16KB RAM and lots of interfaces including USB Host, USB Device, SPI, I2C, ADC, DAC, PWM, Touch Sensor and other I/O interfaces.

The mbed platform provides experienced embedded developers with powerful and productive tools for building proof-of-concepts. For developers new to 32-bit microcontrollers, mbed provides an accessible prototyping solution to get projects built with the backing of libraries, resources and support shared in the mbed community.

Next step¶

The next thing to do is download a pre-compiled program, so that you get used to downloading and running programs before you start compiling your own.
