More than 6 years after the release of its first electronic Compass for consumer applications, Yamaha has released its third 3-Axis geomagnetic sensor.

In a market largely dominated by AKM, Yamaha has launched its new very small eCompass, 1.46mm x 1.46mm, based on a GMR principle, in order to gain market shares. The manufacturing process combines GMR deposition and surface micromachining , allowing to measure the 3-axis with one die. The YAS532B has the same performances that the new AKM device with an area 17% smaller.

Manufactured in a old foundry amortized, the YAS532B is very cheap.

The YAS532B integrates an ingenious magnetic concentrator.
