Features:

  • MS5803-14BA Pressure Sensor Breakout
  • High resolution pressure sensor
  • Both I2C and SPI interfaces
  • MEMS pressure sensor
  • Measures the absolute pressure of the fluid around it
  • Works for measuring the pressure in air, water, and any other viscous fluids
  • Useful for determining altitude, water depth, or any other tasks that require an accurate pressure reading.
  • What makes the MS5803-14BA unique is the the gel membrane and antimagnetic stainless steel cap that protects against 30 bar water pressure.
  • Resolution range of 1 / 0.6 / 0.4 / 0.3 / 0.2 mbar
  • Solder across the two solder points to jump and switch between I2C and SPI interfaces
  • Address 0x76 or 0x77 selectable by solder jump for addressing multiple boards at the same time
