DIP switch 3 interfaces with the BOOT pad of the module and allows the user to upgrade the Flash memory. For normal operation the switch should be set to OFF. To boot from the serial port the switch should be set to ON. This switch is enabled by the internal switch SW3.3. 3.2.4 DIP switch 4 – GPIO1/W_TICKS input DIP switch 4 interfaces to the GPIO1/W_TICKS pad of the module. The switch is typically OFF, but has no effect with the standard module’s software. This switch can be enabled by the

The gyro should be mounted so that its sensitive axis is as near vertical as practical. Deviations from the vertical will reduce sensitivity for heading changes in the horizontal direction. Experiments have shown that acceptable performance can be achieved with mounting deviations of several degrees, but a better performance is achieved when the gyro is mounted closer to vertical.
