What is it?

A high-precision magnetometer for small unmanned aircraft. Includes a high-quality Memsic MMC5983MA magnetometer enabling sub-1-degree heading accuracy. This interfaces to your autopilot via robust UAVCAN interface - no sketchy I2C wiring for your magnetometer! Comes fully assembled, ready to use!

What makes it special?

• Extremely high-quality Memsic magnetometer IC allows ~0.5deg heading accuracy in low-interference installations
• Robust UAVCAN interface is compatible with most Pixhawks and similar autopilots and makes it safe to install this out in a wing or wherever is convenient!
• Update firmware via CAN interface

Why did you make it?

Stock GPS "pucks" include a magnetometer that interfaces to the autopilot via I2C, which is a board-level interface - it should never be used for long-distance communications. This makes it difficult and dangerous to mount your mag anywhere far away from your autopilot, so you can't really get it far away from power sources and other interference that messes up your heading measurement! There are also no real choices for ready-to-use, standalone magnetometers out there - they're only included in GPS "pucks".
