This is the MS5803-14BA Pressure Sensor Breakout, a high-resolution pressure sensor with I2C and SPI interface. This MEMS pressure sensor measures the absolute pressure of the surrounding fluid, which includes air, water and everything else that acts like a viscous liquid. Depending on how you interpret the data, you can determine height, water depth, or other tasks that require accurate pressure measurement. What was unique to the MS5803-14BA is the gel membrane and the anti-magnetic stainless steel cap, which protects against 30 bar water pressure.
We have broken out all the pins you need, including GND and 3.3V for power, SDA/SDI and SCL/SCLK for a I2C interface and SD0, AD/CS and PS for an SPI interface. The MS5803-14BA breakout offers a resolution range of 1/0.6/0.4/0.3/0.2 mbar. Please note that switching between the I2C and SPI interfaces requires a little soldering between the solder pads, please read the connection description below for more information.
