GPS, Compass & Magnetic

The Locosys LS20031 GPS receiver integrates a MediaTek MT3329 66-channel GPS chip with a ceramic antenna to create a complete GPS module that can track up to 66 GPS satellites at a time. Supports a 10Hz update rate, TTL serial and includes a battery for rapid satellite acquisition and more than 6 different NMEA ASCII sentences. More details...

This IMU from CH Robotics is an Attitude and Heading Reference System (AHRS) that combines three gyro axes, three accelerometer axes, three magnetic compass axes, and a powerful 32-bit ARM Cortex on one tiny, 2.7g board reporting yaw, pitch, and roll angles at up to 300 Hz over a simple TTL serial interface.

The CMPS10 module is a tilt compensated compass. Employing a 3-axis magnetometer and a 3-axis accelerometer and a powerful 16-bit processor, the CMPS10 has been designed to remove the errors caused by tilting of the PCB. Powered from 3.3-5V @25mA the compass outputs the bearing reading via serial, I2C or PWM interface. More details...

With the addition of a breakout board the surface mount Honeywell HMC6352 IC becomes a compass module ready to plug into any project. Using an I2C interface the module is able to communicate with most microcontrollers. More details...
