with extended functionality

Freescale is now offering the next generation RD3965MMA7660FC: ZSTAR3 with MMA7660FC accelerometer that offers extended functionality. New software has been developed to allow the user to tap, shake or orient the device with the RD3965MMA7660FC: ZSTAR3MMA7660FC for specified commands. The ZSTAR3 digital and analog accelerometer boards, connected through an RF ZigBee® 2.4 GHz communication to a single USB node connected to a PC. The MMA7660FC accelerometer board measures acceleration in three axes using a pin compatible digital or, optionally, an analog sensor. The sensor sensitivity is defined by the MMA7660FC accelerometer. The USB node is part of the ZSTAR design, equipped with dedicated software supporting multiple nodes.
