The Digilent Pmod CMPS2 is a digital compass module using Memsic's MMC34160PJ magnetometer. The local magnetic field strength can be measured in a ±16 Gauss range with a heading accuracy of 1° and up to 0.5 mG of resolution.
Features:
Low noise 3-axis digital compass
0.5 milligauss field resolution in ±16 Gauss fields
I2C Slave, FAST (≤400 kHz) mode
Optional pull-up resistors for SCL and SDA pins
1° heading accuracy
Small PCB size for flexible designs 0.8" × 1.25" (2.0 cm × 3.2 cm)
