A 0.8 x 0.4 inch (21 x 10 mm) breakout board with the ALT002-14E Tunneling Magnetoresistance (TMR) analog bridge magnetometer.
The board has a pre-soldered sensor and footprints for a standard 0.1" (2.54 mm) header and a common, 1 mm pitch card-edge connector.
The board can be powered by a 0 to 10 V supply and provides a linear, differential output voltage.
The ALT002-14E is an ultraminiature, ultrahigh sensitivity Tunneling Magnetoresistance (TMR) analog bridge magnetic sensor. The differential bridge
output is bipolar, meaning it is positive for a positive field and negative for
an opposite field polarity.
