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 I2C 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.
