The Cricket Developer’s Kit, MCS-KIT410CA, is an entry-level kit for
Wireless Location System Development. It features MEMSIC’s MCS series
Cricket Mote (MCS410CA). The MCS410CA is a location-aware version of
MEMSIC’s popular MICA2 low-power Processor/Radio module. The MCS410CA
includes all of the standard MICA2 hardware along with an ultrasound
transmitter and receiver. The addition of this Ultrasound technology to
existing RF devices allows the Cricket Mote to derive linear range
estimates by establishing differential time of arrival between these two
signals.
