The Altimeter Module is a high resolution (20 cm) altimeter sensor with SPI and I²C bus interface.
The module includes a high linearity barometric pressure sensor and a high resolution temperature output, allowing implementation of an altimeter/thermometer without any additional sensors. Different operation modes allow the user to optimize for conversion speed or current consumption. The module is designed for use with a large variety of microcontrollers with different voltage requirements.
