Bosch’s BMP580 is a precision barometric pressure, temperature and altimeter sensor for projects that need fine height or pressure tracking. It follows on from Bosch’s BMP2xx and BMP3xx sensors and can be used over either I2C or SPI.
Use I2C for simple wiring, or SPI when you want to connect multiple sensors without worrying about I2C address collisions. The BMP580 is software/firmware compatible with the BMP581, but with less accurate/precision measurements and a lower cost.
Adafruit has mounted the surface-mount sensor on a custom PCB in the STEMMA QT form factor. STEMMA QT connectors on both sides are compatible with SparkFun Qwiic I2C connectors, making it easy to make solderless connections or chain it with compatible sensors and accessories. A QT cable is not included.
This sensor suits drones and quadcopters for altitude stability, as well as wearables and projects that track height above sea level. Like other pressure-based altimeters, absolute height still depends on entering the sea-level barometric pressure as the weather changes.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
