Freescale Freedom dev board hosts Kinetis K next-gen MCU: in distribution

August 06, 2014 // By Graham Prophet
Farnell element14 has the Freescale Freedom FRDM-K22F development kit; the board hosts an ARM Cortex-M4 based MCU and comes with 6-axis accelerometer and magnetometer IC, plus demo applications for ecompass, metal detector and air mouse.

This is the second Freedom board featuring a Kinetis K next-generation microcontroller and crystal-less USB controller. It is targeted at USB applications that require a high level of integration and the lower-power capabilities of the new generation of ARM Cortex-M4 core; running at 120 MHz with Floating Point Unit it embeds 512 kB Flash and 128 kB RAM in a LQFP64 package.

The development board features a 6-axis accelerometer and magnetometer, RGB LED and Arduino R3 I/O connectors, and the new OpenSDAv2 serial and debug interface. It is suited for applications which require a high performance and low-power MCU, including: home and building automation; industrial / commercial sensor nodes; Internet-of-things data concentrators; health and wellness monitors, sports and activity wearables; and gaming accessories.

Included in the K22F are out-of-box demo applications; Bubble level - red and green LEDs indicating level; eCompass - indicating magnetic north; USB CDC demo - second serial terminal; Metal detector - direction and distance to a metal object; Stopwatch - real-time counter with 1/100th of a second precision; air mouse; USB mouse to determine where/how to move the cursor.

The Freescale Freedom K22F is priced at £19.98 (UKP, or equivalent).
