+# Boardoza MS5611 Barometric Pressure Sensor Breakout Board
+
+The **Boardoza MS5611** is a **high-precision barometric pressure sensor module** designed for **altitude measurement, weather monitoring, and industrial pressure sensing**. It integrates the **MS5611-01BA03** digital pressure sensor, providing accurate pressure readings with ultra-low power consumption.  
+
+This module operates with **3.3V or 5V**, making it compatible with a wide range of microcontrollers. It communicates via **I<sup>2</sup>C by default**, but can be switched to **SPI mode** using the **PS pin**. The **CSB, SDO, and PS pins operate at 3.3V**, ensuring easy interfacing with low-power microcontrollers.
