are drawn by the wind sensor (whenever enabled) at 4 Hz rate, which is
the default value for wind sampling. Wind sampling at 2 Hz or 1 Hz rate
is also available (see
Chapter 8, Sensor and Data Message Settings, on
). The average current consumption will decrease almost in
proportion to the sampling rate, since wind measurement is the most
consuming operation in the system.
In most occasions the average consumption is less than 10 mA.
Typically, the higher the voltage the lower the current (see
