just realised something weird about sparkfun 5dof.
besides interfacing with my mcu, i left wires connected on gyroX and gyroY pins actually, for easy probing when i have to. normally i left the other end of the wires unstripped to avoid any shorting. however, when i start up the system one day, the X and Y biases dropped like 0.2V. When i stripped the wires, the X and Y biases were back to normal again. does anyone know what could the reason be? i'm not an electronics expert
