Freescale Kinetis based Mbed IoT Starter Kit Ethernet Edition Connects to IBM IoT Cloud

ARM, IBM and Freescale have jointly announced Mbed IoT Start Kit – Ethernet Edition at Embedded World 2015 that consists of  a Freescale Kinetis Cortex M4 mbed-enabled development board and a sensor IO application shield that interface with IBM Bluemix cloud platform.


Freescale FRDM-K64F Freedom development board specifications:

  • MCU – Freescale Kinetis K64 (MK64FN1M0VLL12) ARM Cortex M4 MCU @ 120 MHz with 1 MB flash memory, 256 KB RAM
  • External Storage – SDHC slot
  • Connectivity – 10/100M Ethernet
  • USB – Dual role USB interface with micro-B USB connector
  • Sensors – FXOS8700CQ accelerometer and magnetometer
  • Headers – Arduino R3 compatible I/O connectors
  • Misc – RGB LED, two user push buttons
  • Power Supply – OpenSDAv2 USB, Kinetis K64 USB, and external source


The board also features a programmable OpenSDAv2 debug circuit supporting the CMSIS-DAP Interface software that provides a mass storage device (MSD) flash programming interface, or a CMSIS-DAP debug interface, or a virtual serial port interface. The board also support RF and Bluetooth add-on module but these are not included in the IoT kit, and instead a shield is provided with a 128×64 graphics LCD, two potentiometers, a joystick button, a PWM connected speaker, a 3-axis accelerometer, an RGB LED (connected via PWM), and a temperature sensor. A Xbee socket can be used to connect a Zigbee or WiFi module.

Getting started with the board is very easy. Connect the two boards, add an Ethernet cable, and a USB connection to your PC. The board will show as a storage device, and you can open IBM.html file to start the user interface in your web browser and monitor and play with the sensor and other hardware parts.

Mbed_IBM_Cloud_Web_InterfaceDevelopment is done via Eclipse and Mbed SDK. Pricing and avaibility have not been disclosed so far, but as reference FRDM-K64F board can be purchased separately for $35, and mbed Application Shield for 31 GBP exc. VAT, so the kit could go for around $80.

Further details can be found on mbed’s IBM Ethernet Kit page as well as a dedicated page on IBM website also including hardware design files.
