Description Boardoza MS5611 Barometric Pressure Sensor is a high-precision pressure sensor breakout board based on the MS5611-01BA03 digital pressure sensor. It is designed for altitude measurement, weather monitoring, UAV projects, and industrial pressure sensing applications that need accurate barometric pressure data with low power consumption. The board operates from 3.3V to 5.5V and uses I2C by default. It can also be configured for SPI mode through the PS pin according to the official documentation. Features High-precision pressure sensing: suitable for altitude measurement, weather stations, UAVs, and pressure monitoring. MS5611-01BA03 sensor: based on the official MS5611 digital barometric pressure sensor. 24-bit ADC output: high-resolution pressure measurement for precise readings. Flexible interface: I2C by default, with SPI mode configurable through the PS pin. Wide input voltage: supports 3.3V to 5.5V operation for common embedded platforms. Compact board format: 20mm x 20mm breakout board for compact designs.
