Good sensor, small pins

The sensor works well but the pins are a bit close together for breadboards without adapters.

Great Replacement for BMP085

Direct pinout match for my old project. Saved me from redesigning the PCB layout.

Accurate Pressure Readings

Used this for altitude estimation in a small drone. Very stable data even during flight.

Needs extra research

Works fine but I had to dig around for example code. Not plug and play for complete beginners.
