Pneumatic module in version 2.0 contain set of sensors for measurement parameters of the air in flight like: pressure, altitude, speed, vertical speed (variometer). Additionally for optimal filling 8 channels of ADC module has 2 inputs for thermocouple and 2 channels for user sensors working in range 0-4V.
Communication with module is done via SPI bus, by reading data from 16-bit A/D converter. Module need 3,3V supply for digital interface and 5,0V for sensors.
From software point of view actual version of firmware measure all parameters, make temperature calibration and individual calibration offset and gain for every sensor.
