0 $3 gyro ? Posted by Howard Gordon on July 14, 2008 at 10:29am I just stumbled across this 300 deg/sec rate gyro -Description - http://embedded-system.net/lisy300al-single-axis-yaw-rate-sensor.htmlDatasheet - http://www.st.com/stonline/products/literature/ds/14753.pdfThey're talking about $2.50 in volume for the chip. It's analog only, which is unfortunate (where's the SPI or I2C interface ?), but at the cost level, might still be a significant breakthrough. E-mail me when people leave their comments – Follow

ADC chips are pretty cheap and simple. I wouldn't say analog is really that big of a drawback if you can get it this cheap.
Here is code for getting the $3 MCP3202 talking to an Arduino over spi.
