CRG20 is a single axis MEMS angular rate sensor.
The attractive cost/performance ratio makes these
gyros attractive to a variety of different applications
where space and cost are a premium. CRG20 gyros
are supplied in a PCBA surface mountable 36-pad LCC
package and are intended to be integrated into a user’s
own electronics.
To aid with product assessment and integration Silicon
Sensing have a development board available for the
designers to easily connect and access the data.
The CRG20 evaluation boards are available for the
standard -01, -02, -12 and -22 variants of the gyro.
Part Number: CRG20-xx-0300
xx is the variants required
CRG20 part mounted: CRG20-01 or CRG20-02 or
CRG20-12 or CRG20-22Size: 21mm x 40.4mm (including pins)
Power Supply: +5V and 0V
Analogue Outputs: Yes
Digital Output: Yes via SPI® interface
Optional: USB interface kit
The boards are not intended to be used as an integral
part of a system. They are available purely for evaluation
and assessment purposes.
