Hi! I need to find right compass for a uav with SPI and I2C. Now I use HMC5883L but time to time it gives very noisy, bad information. I need high accuracy low noise compass.
Welcome to the Digikey forum. Here are some options we have in stock to look at. They do have SPI and I2C outputs , you will want to verify the voltage supply and package types to see if you can implement one of these with your UAV.
Here are some additional compass IC’s to consider. Note that some of these only have I2C interface, rather than both I2C and SPI.
