The PAK7620H1 is an ARM mbed and Aduino enabled development board for use with mbed enabled platforms. This development board is suitable for use with developing application using PAJ7620 as a gesture recognition sensor where the built engine makes the integration very practical.

The PAJ7620 is an integrated package with our proprietary CMOS image sensor, optics and an IR LED. The fully integrated package eliminates the need to source these parts individually to realize your gesture applications.

For more information on how to setup and run the PAK7620H1with nRF51 DK, please also visit the Wiki Page to learn more:

In addition, we have also tested it on Nucleo, NXP/Freescale Platforms. Please see Tested Platforms for more compatible platforms. Do not see your platform of choice? Please let us know.
