SC1221AR3-B-122

Evaluation Kit for CMOS 60GHz Radar Sensor
 Overview“The 2D location sensing evaluation kit (EVK),SC1221AR3-B-122, provides an evaluation
environment of the Socionext 60GHz RadarSensor (SC1221AR3).

Sensor Board

Interface Board

The EVK consists of EVK main unit (sensor board,interface board, and DragonBoard™*), accessory,and the software package which is to be used
under the host windows OS PC connected with
the EVK via a USB cable.

Notes : In order to detect objects on theEVKUSB Cable

ground, the EVK should be faced to thedetection target area, for example, placing
it on the wall or with a supporter like a
tripod stand as shown in the right figure.
