digital compass for ADC
« on: March 09, 2007, 04:26:09 PM »
Does anyone know where I can get a tiny (smaller the better) digital compass that can give an analog value output for an ADC on a microcontroller?

If it outputted a PWM, I could run that into a capacitor for an output analog voltage . . .

the best I can find is this but its been around for years and its still a little too big for me:

oh and cost doesnt matter ;D

Admin,

This one is I2C, but it certainly fits the tiny criteria:

This one is true analog:

Nice thing with that one - if it works for you, you can build your own board - the 2-axis chip itself is cheap and tiny...
