cheap digital compass, does anyone have experience with it?
January 16, 2011
Hi LMR people,
Looking for a digital compass for my robot, I found this interesting Dual-axis Magnetic Sensor Module with UART& I 2 c Interface for $16.
does anyone have experience with it? I noticed there is also a cheaper version without the usart function for 5 dollar. http://www.sureelectronics.net/goods.php?id=944 sounds really cheap, but does it work good? anyone already used one of these?
