BMP388L BMP390L I2C Barometric Pressure Sensor 24-Bit Module

Take your embedded electronics projects to the next level with this I2C/SPI Barometric Pressure & Temperature Sensor Module featuring both the BMP388L and BMP390L chips. With 24-bit high-resolution sensing, this compact dual-module bundle is ideal for drones, weather stations, altimeters, microcontroller projects, and any application requiring precise atmospheric pressure and temperature readings.

Why This Sensor Module Stands Out

• Dual-Chip Bundle: Includes one BMP388L and one BMP390L module — perfect for comparing performance or running redundant sensing in critical builds.
• 24-Bit High Resolution: Delivers highly accurate barometric pressure readings across a wide 300–1250 hPa range, suitable for altitude tracking and environmental monitoring.
• Ultra-Low Power Consumption: Sleep mode draws just 54 µA; normal operation runs at 357–650 µA — great for battery-powered and energy-sensitive designs.
• Dual Interface Support: Compatible with both I2C and SPI communication protocols, giving you flexibility across Arduino, Raspberry Pi, ESP32, STM32, and more.
• Wide Operating Range: Functions reliably from -40°C to +85°C, making it suitable for both indoor lab environments and demanding outdoor applications.
• Compact Footprint: At just 19×19 mm, the module fits easily into tight PCB layouts and DIY enclosures.
• Broad Supply Voltage: Operates at 3.3V–5V, compatible with virtually all common microcontroller platforms without additional level shifting.

Frequently Asked Questions

Q: What is the difference between the BMP388L and BMP390L sensor modules?

A: Both the BMP388L and BMP390L are high-precision 24-bit barometric pressure and temperature sensors. The BMP390L is an updated iteration offering improved accuracy, lower noise, and enhanced long-term stability compared to the BMP388L. Receiving both in this bundle allows you to evaluate both chips side by side or use each in a different stage of your project.

Q: Which microcontroller platforms are compatible with these sensor modules?

A: These modules support both I2C and SPI communication protocols, making them compatible with a wide range of platforms including Arduino (Uno, Mega, Nano), Raspberry Pi, ESP8266, ESP32, STM32, and most other 3.3V–5V microcontrollers commonly used in embedded and IoT development.

Q: Can I use these modules outdoors or in temperature-extreme environments?

A: Yes. Both modules operate reliably across a wide temperature range of -40°C to +85°C, making them well-suited for outdoor deployments, drone flight conditions, or industrial environments where temperature fluctuations are common.

Q: Are these modules suitable for altitude measurement in drones?

A: Absolutely. The 300–1250 hPa pressure sensing range and 24-bit resolution make these modules excellent for drone altimetry and flight controller integration, providing the accuracy needed for stable altitude hold and height estimation.
